I Lost the Leash of the Yandere Male Lead


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

I transmigrated into a novel and became the villainess, Serina who comes from the noble Ducal Melford family.

As a well-to-do character, I tried to mind my own business, but the story had other ideas. A self-proclaimed mother brought back a boy – the duke’s heir and a genius wizard – intent on brainwashing and blackening him.

The contents of brainwashing are two things:

1. Obey our family.

2. And fall in love with Serina.

Thanks to that, the brainwashed twisted yandere is obsessed with me…

I can’t do this. I have to undo the twisted character’s brainwashing!

By the way, what’s this situation?

“Now that the brainwashing is gone, I’ll do as I please. So Serina, please, let’s do our best.”

I’ve solved his brainwashing… but why does he seem even crazier than before—

Did I make a mistake?

I got into the novel bc I liked the manhwa so much and couldnt wait to read more about what was happening, and I loved the novel so much more!

I rly love how realistic the characters are and seeing their thought processes. A big theme in this story is about human selfishness and how the world is full of ppl trying to achieve their own desires. The MC may seem like a good person due to her wanting to break MLs brainwashing, but the reasoning for it is a complex... more>> web of love, guilt, and her desire to alleviate her own guilt. Some ppl may hate how she acts like a villain and makes "bad" morally unsound choices, but I understood all her actions and didn't find them weird or unlikable.

Her and MLs relationship is unlike any other I've read, so it was quite interesting to see what they'll do next and how their true feelings are revealed and change.

For instance MC was so sure she could withstand anything from ML after breaking his brainwashing, but she didnt consider how far he would go to stay w her. This led to MC realizing how much she valued her own freedom of choice and how it outweighs her feelings for ML.


The most fluff you'll get is from before the brainwashing ends (which is only like the first half of the novel), so don't expect too much afterwards. Ofc this a is a romance, but their relationship is more like war than love. These characters dont reveal their feelings through the normal means that we would understand, rather through taking action to do what they think is best for each other.


The first side story lays out how the MC came back to life and how she meets her brothers again. Basically it is implied that all the characters MC loves will reunite soon and live happily.

I was disappointed that we didn't get to see MC and ML finally have a sweet fluffy moment til the end. I also wanted to see their kid, but I'm assuming it will take a long time before that happens which is why it wasn't written.



The second side story is the story of the original novel. It's like both stories are parallel universes where one tells the story of the MC dying and the other tells the story of the ML dying.


All in all I loved this story and would recommend to angst lovers and those who would like a unique read. <<less

I'm surprised that it has such a low rating...I actually love the novel. The premise is pretty unique imo and omg I love the dynamic between her and her brothers

fMC fights with her older brother to obtain an invitation and he loses.. lol later while he's recuperating in bed he laments abt how much she's grown and how he cant protect her as much anymore

hopefully the translator continues to update this novel!!

Sad part, there was no free chapters to read like mtling it. Huhuhu so I have to wait for it to be translated. And sad part is, it is cut into two parts so as always making me hunger for more.

Anyways, the story goes like this...

... more>>

The ML being brainwash by MC's mother, successfully made him love the MC. Although MC is a reincarnated person, she doesn't usually utilizes it and just watching things unfold as she couldn't do anything to stop her mother. Though, she is always there for ML as thinking ahead of curing him (brainwash) in the future. Sadly at the start, when he slightly recovered, he tried to kill the MC as he hated her (according to what she saw in his eyes). But still before he could do it, it's either he failed because the antidote didn't fully disinfect him or that he couldn't truly kill her. So now, he is still obsessed over the MC going so far as to wait for her and interrupt her in bidding the elf (as one of the helpers for finding the cure of the ML) as he was curious as to why she wasn't interested in anything he had given her and so when he followed MC as MC's brother told him about the MC's whereabout, he was very jealous as to why she picked that MALE elf. Well, the auction was interrupted midway due to the male protagonist of the story raiding. That is till the latest heheh...


I enjoyed it while reading tho. The translation is good. There are some grammatical error but will do. <<less

The story is interesting, very interesting till now. Unlike transmigrated MCs who turn super-OP and solve ALL problems in one shot, MC is weak, helpless and unable to do anything at this point of time. This is a realistic change from the usual trope and how she goes about trying to achieve her goals is pretty nice.

T/L - 5/5

If you are looking for a story with heavy angst and a complicated romance, this is a good one. It was interesting to watch the FL and ML interact, the whole brainwashing ML to love FL is an interesting plot which gave each romantic scene a bitter tension that made reading kind of exciting but also nerve-racking.

The ending was very satisfying for me. I read a lot of typical happy ending josei stories so it was refreshing and heartbreaking to read out a story like this. This story doesn't have... more>> a completely happy ending, which I think was fitting for the plot. <<less

It’s been a long time since I last read something like this on NU. My favorite type of “killing me softly” where you feel your chest hurt with the entanglement between the main characters. It’s the kind of story that you feel heartache over not knowing if it will end in tragedy or not. I love the premise of the story and the main leads. Such a gem!

I love this novel and very recommended it. Even tho there is some inconvenient in the novel's next chapter button as only sometimes that it brings you to the real next chapter and otherwise a completely different novel's chapter. So the only way to go to the next chapter is to go back to this page and choose the chapter you want 🙁🙁. But let's put that aside, the story is more interesting for you to care about this kind of inconvenient thing. It was very entertaining and a very... more>> serious type too. It was totally my cup of tea so I don't really understand the low star review, maybe because the inconvenient that I just mentioned. This is not your typical novel (well maybe, it's just my opinion) and I very recommend to read, just turn a blind eye on the inconvenient and you will see how beautiful the novel is. <<less

I keep saying this about every novel but I feel like this is really the best one I've read so far. As far as I can remember, I don't recall any severely disturbing typos or grammatical errors, and I'm more than content with the pacing and plot of the novel. From an early point you can see the yandere-ness of the male lead, and I can't help but applaud this, because I've never read a novel where the yandere was actually yandere enough to satisfy me (why does this sound... more>> pe*verted). I'm very VERY satisfied with ILLYML. The only complaint I have is that chapters are split into two and I get impatient with the updates, but I know the translator is giving their best effort and am immensely grateful for them. Highly recommend this, but maybe read it after a dozen more chapters are out so you don't have to wait so much! <<less

i saw some spoilers about this novel. Hope they were false :' (I love them so much especially the male lead. And our female lead is not s*upid. The writing style is perfect, I felt ever little thing. This novel gave me lots of emotions that I hope the manhwa would be like this too.

I couldn't keep up with the translation. I nitpick at the smallest things so this review is for me alone, not everyone else. I just need to leave a small reminder that I've gone through this and didn't like it.

Small reminders that will help me remember this novel ↓

... more>>

*The mother is in charge of the title. Translator can't seem to figure out if they should address her as either Duke or Duchess. So sometimes they choose both. (A little bit annoying.)

*MC is the weak type. (This wasn't so bad. Actually was one of the most refreshing part of the novel, really.)

*Dragged a bit and suddenly lost interest.

*Translation issue... again. Sometimes I got lost and didn't know the author switched scenes already.

I normally never get around to reviewing things, but this is so damn good that I thought it would be a disservice to not sing its praises for people who are considering reading.

The characters are emotionally complex, the magic is interesting, and the plot is the most unique I've come across in the transmigration genre. Plus, the translation is well done!

Overall, I love stories with strong FLs and submissive MLs, and I think this is the best one I've read so far. If all this stuff sounds like your jam,... more>> I strongly recommend giving ILLYML a try. <<less

Great novel for those who love angst, but since I don't I'm not going to put stars for this since my bias would denounce that it is a good novel for angst, just not my cup of tea. The beginning imo seem like bait as I was hoping to read a romance novel with a yandere ML but instead romance was pretty lacking midway to the end as the plot focused more on the setting and the backstory. I ended up being more interested in FL's mother's story more since... more>> FL's romance got too angsty for me to enjoy and I just gave up on the romance. Focusing on the twins and the mother's story allow me to finish the novel. Otherwise I would've dropped it. <<less

MC and ML's relationship is so bitter-sweet it's heartbreaking. Reading through this novel is an emotional rollercoaster, except the tracks are always plummeting downwards. It's so painfully tragic, and that's what gives this novel its shine.

MC is a villainess. ML is brainwashed. Childhood friends. Twisted relationships. Misunderstandings ensue. ML is so pitiful it hurts, and MC is so lost she hurts ML, but ML never gives up. His undivided devotion to her is insanely admirable.

Waiting for new updates will be a difficult and arduous period of time. I treasure this... more>> novel that much. <<less

Gotta say that the manga has a faster update speed n is already ahead of the novel.

love the twisted dynamic where she thinks she knows that

he doesn’t love her just brainwashed then it turns out that the backstory is more than that. Romantic :) and also ML is kinda pitable

It's boring. That's it. I love the concept, it's something that if written well could be great but I'm having a hard time reading it. The pacing is way off and I find myself having to take multiple breaks just to get through a chapter. I might get better later in the book but currently, I can't force myself to continue reading.

i feel like there are so many ways in which this novel could go wrong, but honestly the author is doing really well!! I love alistair for obvious reasons and and I LOVE serina because shes a little selfish and flawed in ways that I can relate too. The translation is also good, as is the usual case with that1villainess

This story isn't perfect by any means, whether it's the characters, the plot, the writing, or the world building. But it hovered just above satisfactory so I continued to read.

Yet I couldn't help giving it a slightly higher rating because one in a while, there are moments that are of higher quality than the rest of the novel, moments that dip deeper into thoughts that I wouldn't have expected from this story.

... more>>

[I cannot be a saint.

I can't be nice.

Just because I 'understand' and emphasize does not make what happened to me acceptable.

Because I am a person who is hurt too.

The pillar that supported me is cracking little by little.]



[I emphasize with him, but I can't sacrifice myself.

I need to protect myself.

I was hurt—there was an angry, sorrowful ache in my heart that made me spiteful and resentful. It leaked poison into my mouth, and I sought relief—and frantically searching for some medicine over it, some relief.

I know very well that I am using the wrong medication that doesn't fit my wounds.

Still, I couldn't stop applying it.]


Despite the fact that I can't gush about the quality of this work, I do have the confidence that the rest of this story that I haven't read yet will not disappoint me.


The chapters (around 27-29) that explore how this all started were phenomenal. As expected, it didn't disappoint. <<less

Love-hate relationships are my thing so Imma just camp here.

So far MC is likable and sensible girl, whilst our ML is batsh*t crazy lol. That's only to be expected tho, he's been drugged for 1/3 of his life. I like their dynamics, I wanna know what happens next asap BUT THERE ARE JUST TOO FEW CHAPTERS-

Also on the side note, translation isn't the best, but still delivers the message across and actually improves over time. So, if you're gonna skip this one just because of sum tl errors, I tell... more>> ya it would be a pity. <<less
