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?

the thing is the novel is dark and shows a love hate relationship between MC and ml

as for the tragedy tag


she dies. There is some power in her blood or something


so any masochists who love angsty stories can camp here. And as for our ml


he goes crazy trying to revive her

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'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

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

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

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 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>> perverted). 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 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

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 didn't expect the ending tho (>0<;) but I guess it was worth it. The ML was a yandere and they had. A love-hate relationship. The villain was her mother who brainwashed these dudes.


bruh the FL died after suicide and ML gone crazy mad scientist to ressurect her body and finally succeeded
