Very intriguing and to be honest I felt it illogical how close the two protagonists were until I remembered,

It's a love simulator.

Meaning the protagonists thinks their love interest (capture target) isnt real.

*flashbacks to caressing handsome cg's of otome games*

Ahem, anyways, can't wait to see the development (///•//v//•///)

The first half of the novel is very tense, emotional, and intriguing, but the second half started to wear on me to the point I just slowly lost interest due to the change in dynamic between the leads. It just slowly got more and more stereotypical with the ML showering gifts onto a talented holy-saint like MC. You could argue that the MC has been like that from the start, but without the threat of immediate death and suffering hanging over their heads, it became increasing flat and lack luster-... more>> for me at least. It just sort of felt like the characters and their relationship stopped progressing.

Credit where credit is due, the first half is emotional and you really feel the weight of the situation. That adventure is almost enough to justify mtling the through the novel even if my interest in where the story was going didn't last. <<less

Plot: Two parties meet across space and time through a "game" called Exclusive Lover. One is a young and struggling novelist while the other is a great General of an interstellar empire. The mysterious game reenacts the general's painful past as a laboratory experiment; except this time, the young novelist also appears in the role of one of the Orphanage's cruel employees.

Edit 2: For me this story will never be able to get above 4stars. I honestly feel like MC is just a normally kind person that does normal things,... more>> but he just happens to be in a position where the powerful ML gets attached and likes him because he has to follow along the plot of the game. In one sense the relationship progression is slow, but it was also inevitable which is something I don't personally like for the same reason I don't like love at first sight plots. Also, his golden finger is pretty crazy.

In addition, I'm not a fan of the "real-life" writing bits, but that's personal preference.

Edit: So far it's just getting better! I don't really care about MC's real life experiences tbh, but that's not too big a part of the story so it's fine

Original Review:

Oh my goodness, too much meng. Tbh I didn't really understand the synopsis but read the story anyway, and so far it's worth it. Excited going forward.

Thanks for the translator's hard work! <<less

5 stars!!


I'm so touched.

... more>> From the MC being a normal person from Earth and the ML being a sick (literally) high ranking soldier from the interstellar age who didn't have a positive outlook in life, then the MC finding this mysterious game and then slowly transforming into his true form (mermaid koi fish) while the ML slowly heals himself and tries to unravel the knots in his traumatic past, and then finally meeting each other in the interstellar age...... This novel is just so good.

I like how the author created this world and even though in the end, it wasn't really mentioned how the mysterious game was created (only implied that it must've come from a much higher realm) I really like how their paths have crossed.

I am so touched by the ML. I didn't feel like the novel was long or dragging. It was very simple.

What really made its mark on me was the extra chapters.

This novel is an mpreg btw.


The ML and MC will be gifted an egg by the game and they will raise their own cubs once it hatches.

The egg is so cute btw.

And if you're curious, they're going to have twins. The oldest is also a little mermaid (boy) with blue eyes and black hair, the youngest is a white tiger with wings (boy) with blue eyes and white hair.


The extras are in a diary form. It's written and is in the point of view of the ML.


If you're gonna read the novel, you'll really feel for the ML since he was also just a baby when he was taken in and used for human experiments. He was depressed, he didn't hate the world — he probably did but its more of a distrust and the feeling of not veing able to feel anything at all.

He expressed his fears of not being a good father. He didn't know how to react or raise the children well since he never had a proper childhood. His childhood was all about "be weak and get killed" and this casted a shadow over him.

He also never experienced puberty since the ML was just injected growth hormones and was forced to become an adult.

He's full of conflicting emotions but this cannot deny how much he loves and treasures his cubs. Especially his lover. The MC is the light of the ML's life.

Sometimes the ML had thought that: "What if it was just a dream? What if the cubs didn't exist? What is the MC didn't exist? What if he's still alone and laying on the bed just waiting to die?" but after seeing the MC's face and his children, all of those thoughts go away.

The ML swore to make sure that his children won't have to worry about anything. He'll make sure that they'll live a normal life.

This novel is quite short (I nevel felt that it was close to the ending since the chapters are short and engaging.) I'm soft about baby cubs.

I'm just so happy for them.

I want to thank the translator/s and editor/s for taking up this novel and I especially want to thank the author for making such a lovely novel. <<less

Very interesting story. No fluff in the beginning whatsoever.

but that is the driving force for the readers to continue reading it.

the author's tirades at the end of some chapters are hilarious! Hahaha not all tho.?

This is a 1malex1male novel. No extra parties no green tea bi**es. Just some very warrisome villains who are good at camoflouge. Mind you this is a thriller romance.

... more>>

He Ruge (MC) has one of the best characterization out of all the novels i've read. He did not come out as mary sue at all. Even at the latter parts.

This is an interstellar/thriller romance/horror novel. But it was not until chapter 71 that they faced each other in reality.

Very good ML also. I kinda liked the fanwei parts the author included. It was written on the side of tge ML. Sorta like a diary he first posted unanimous online then madevit private after.

The title and the summary would have you believe this is a story about a mermaid and a general... That's what I was expecting and wanted. I'm 7 chapters into the story and its like watching someone playing an otome game where you click "yes" or "no" options and watch the interactions. Not sure when the mermaid story actually starts, but I'm too impatient to try and click through the rest of the chapters to find out.

Interesting story and the driving force to continue reading is there. All the characters are very likeable too, although I wish the MC could be brighter.

... more>>

It actually took him around 40 chapters, 2 cubs he like, and a friend (?) to realise that him doing nothing but watch also makes him a perpetrator albeit at the same time giving the 3 cubs hope and feeling sorry for them, which in the end still ended with 2 cubs dying.

I actually think him saying that he likes the 3 cubs is hypocrisy because he never thought of saving them. Or maybe he just never liked them that much. Until the little monster told him about the "bullying" anyway.

There were even clues in the early stages of the game like; the rabbit asking him to sing.


The story is interesting but the MC is too slow for my taste.

But then again, I'm just reading through MTL so my brain might have been so damaged or the translation so broken that I missed something. <<less

I wanted to rate 4.

Very Emotional and Touching.

Not the common adventurous dashing clever MC or ML who overturns all plots against them. Both MC and ML have insecurities and are hurt. They heal each other.

... more>> The characters feel genuine and you feel for them. Their stories are heart wrenching. There is no real face slapping. What makes it so good are the thoughts of the MC and ML throughout the novel. The plot is solid.

The side stories about their kids are also very touching. You can literally feel how much the MC loves his kids. And its real cute too. I think people who like to read more realistic love story BL novels might like it too despite the setting being purely fantasy as the characters and their stories are well developed and the feelings are max. I would give this full rating if not for the sudden twist towards the end of the novel that messed it up some. The ending is not satisfactory. The mystery behind who is the evil behind the scenes is unveiled and the answer is too nonsense....


Only con of this novel I feel is the reincarnation part. So the mysterious mastermind behind the ML's suffering and the experimentation program is found out to be himself from his past life?? And then there is the side villain who barely got acknowledged and then died within a chapter or so.

Its like you feel love and pity for the character for his tragic life to find out in the end it was sort of fake as his past incarnation set himself up for this for some reason. Feels like crazy mind games. Also about their previous incarnations being god beasts basically god in this life is too meh. Could have done without these crazy twists in the plot.


But the cute and touching side stories make up for the less than satisfactory ending. Its worth reading for those who like touching love stories.

And for those who feel its boring because of the MC and ML interaction being only through an game with "yes" or "no" options, there is a transmigration and transported to another world tag though it takes till chapter 72. Also the game becomes not really a game and both meet other characters in real life too. <<less

This novel was the exact amount of fluffy and angst I was looking for. The novel is mostly fluffy, so much that I had to take a break and squeal sometimes, but the heavier parts of the plot are still there and written so beautifully.

The ML had a hard childhood which affected how he deals with things as an adult as it should, and just makes him so much more interesting. This is one of the few ML that I actually LOVE with all my being and wish the best... more>> for in everything. It's so cute how he keeps growing and his character growth and relationship development with the MC makes me believe in love and that they truly are soul mates.

There are also children in the extras though no mpreg and it just made me love the novel even more because those are mostly in the pov of the ML and he is my favourite character which is really rare, which goes to show how much I love this novel. 10/10 would read again <<less

This novel looks like a sweet and beautiful love story. But actually it has a lot of torture and world despair. I actually like it because the MC is a singer and can sing war songs to boost the morale. This is the second MC that I like, Yan Mo from banished of the primitive can dance to boost war morale while here sings.

The extras make it perfect. The relationship between the ML and their children are so realistic and touching. Definitely a much more mature take on parent-children relationship.

ML still have a trauma from his past in the lab but he's tryibg to be better for his children. Gotta be one of the most mature father in novels.

Warning to all readers: Our 2 protagonists do not meet in person until chapter 71.

Get some snacks and settle in for a long sotry. there is a lot more going on then the bathtub scene we all desperately want (and were promised by the title).

Summary: A young novelist (of the 21st century) gets a mysterious game he thinks is a cute cub raising sim. Turns out it is actually a sifi/horror adventure game. Turns out it is also a depiction of real events (in the far future), and the "cub"... more>> he is raising is another player... the sifi era general who first experienced those events and is reliving them as part of exposure therapy. The two slowly bond in the game as they try to uncover the true mysteries behind the evenrs that happened in those years. <<less

Much darker than I first assumed based on the description but has very good storytelling, actual character development (& moving characters), and a really good translation quality.

I am only on the first part of the novel but I'm giving 5 stars already because it deserves it. Idk how the latter parts of the novel are. I feel like the author is really good at making you get attached to the characters. There are fun moments, esp in the beginning but there are such heartbreaking moments too. I cried so much. Really did not expect this.

Both fluffy and bloody. I'd say the best out of the current BL horror games that I am currently reading. Unfortunately, it seems that the translator got caught by real life and the last response was almost a year ago.

Ok, ok, ok. So I really need to write a review for this story because it is not what you think it is. If you want to read something fluffy... well, there is fluff and mofumofu. But that's not all it has.

This is the type of story that touches you because it doesn't hide the ugly gore and tragedy in the background but instead brings it to the fore together with the fluff. It is cute. It is gory. It is sad. It is beautiful.

The first few chapters might confuse... more>> you, so here's a bit of an explanation:


He Ruge (MC) and Xi Guican (ML) both live in different worlds. He Ruge seemingly lives in the normal modern world as a writer, while Xi Guican is a general/marshal from the interstellar era. On top of that, Xi Guican is a white tiger beast person with a tragic past.

Both of them end up finding a game and playing it, with differing genres. He Ruge is attracted by mofumofu and played the game thinking it was a romance game, Xi Guican is a face-con so he got suckered by He Ruge's face, but he was initially convinced that it was a kind of game therapy that explored his tragic past. (Cue injured marshall with volatile spiritual power)

The two meet through the game.


This story is amazing because it is so fantastical and yet it sucks you in and makes you empathise with the characters. You will go through the five stages of grief. You will even get


. You will amazingly also explore functions of game systems that would be unrealistic in reality yet in here are an indication of a hidden shadowy hand.

TLDR; The writing is amazing, it will make you cry. The plot is amazing, it makes your IQ hurt. The characters are amazing, they are not 2D. Not even side characters. <<less

Deceived by the title into it thinking it's a fluffy novel! 😅

From spoilers, I can tell that they don't meet up IRL till ch.70 & the story itself isn't my cup of tea...

It's well written, but not what I'm in the mood to read, so I'm ditching it

its a good book, not great bu an ok read.... it could've gone better but I think my expectations for this were a bit high and I was just slightly disappointed with the main story line. Honestly for an interstellar book there can be a lot more than that but then again I skipped a bit towards the end.... oops...i think it has more to do with the MTL making a few things different and me being unable to comprehend what was going on in some chappies...

i still gave this... more>> novel 5 stars tho

3 starts for being an ok read and two stars for the ending and extra chapters.... oh my god it was the best part of the whole freaking book....i was in tears and emotional the whole time, made me think of my own father and think how much he loved me even in places I couldn't see... its a gem that ending. And honestly it made me rethink the ML on a whole new level, and made me understand him in depth. I was satisfied, extremely satisfied.

if I do have any regret it would be how little we are shown about the other son, sometimes makes me feel like his eyes could only carry one child and the other was a bit over-looked...i mean I know he was loved too maybe a bit more by the MC, but ughhhh idk.... anyways im super happy with how the book turned out.

thank you authors and translators. <<less

On hold for now while waiting for more chapters. I didn't have much hope but I was surprised by how much I loved it. Be warned though. The tragedy tag is what nearly turned me away, but while the events for the main leads don't exactly end tragically (as far as I've read at least, I HOPE they'll end up together) but the story is more gory than I expected. Not full on gore but kind of depressing and bloody:

... more>>

Lots of little cub death while the MCs are still in game mode, now it is a game, and it's not described too vividly, but they are basically tortured and die in horrible ways. Yet somehow the text manages to be sweet in some lines. You have to keep in mind, too, that the game is based on the ML's experience while he was a cub (sort of, but that's another story) so all those horrible things happened and those poor test subjects, most of whom were orphaned cubs, were like locked up, abused, tortured, and killed.


The translator thankfully has trigger warnings in each chapter, but the tragedy tag is there for a reason. <<less
