I Couldn’t Stop my Childhood Friend from Turning Into a Villain


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

I was reincarnated in an R-19, psychological novel, where the sub-male lead was blinded by jealousy and imprisoned his sister, the heroine, whom he doesn’t share a drop of blood.

The problem is that she was reincarnated as the childhood friend of the sub-male lead.

She was killed by the villain as the character who tried to help the heroine!

From now on, she can prevent a terrible future by preventing this guy from becoming a villain.

For years like that, she struggled to stop her childhood friend from turning into a villain.

“Lucy, what are you doing there?”

“Go away! You can’t look!”

Or preventing him from seeing the heroine being confessed to…….

“Your sister has brought you flowers.”

“T-The deal the woman gave you?”

It was basic for her to say nonsense.


It is no exaggeration to say that she devoted her entire childhood to twisting the original.

But why…

“Let’s go back, this is not where you will be, but my room.”

Why is he trying to imprison her instead of his sister…?

“Let me bite your ankle once. Then I’ll let you out of here.”

If she gets bitten, he’ll be able to see where she is and what she’s doing!

However, it seemed that her voice could not reach his ears.

It’s not only that she couldn’t stop her childhood friend from becoming twisted, but she’s going to be prisoned as well.

It's still early to give a review but all I can say is that this novel has potential!! Cordelia (the ogFl) is giving the kind older sister vibes and is happy to see the two kids (Lucy and Liel) bonding and opening up to each other. It was also hinted that even before remembering her past memories, Liel already fell in love with Lucy (and Cordelia was the one who noticed it). Liel's love language might be physical touch and them holding hands makes my heart throb for my cute... more>> babies. I'm so happy to see translator-nim updating every single day because I'm dying to know more about each character. <<less

This novel is pretty awesome and it's funny, the female lead is a little oblivious and the main lead comes across as yandere.

The male lead's so-called sister the original female lead is a sweetheart she's this sweet older sister to both the male and the female leads.

... more>>

to make clear things the original female and the male lead are not siblings, the ML's mother was an un-request love of the Duke the original female lead's father.

The mother wanted to protect her son after she is dead, but she doesn't confirm who's the child's father, and the Duke is in delusional State thinking the child is his.

The sister is aware of the male lead's dark side, and the female lead tries her best not to make him evil but still, you know you cannot change a person's nature completely yeah like after some chapters he starts overly obsessing over the FL and he takes hold of her, it's the time where his hair change the color.

I started reading because of the lovely illustration and also because I have a fascination with yandere male leads.

The translations are okay. Although there are times where one might get a little bit confused with transition of first to third person point of view (sentence construction), it's generally very much understandable and still good to read. And it is such a plus that updates are regular.

Story-wise, I like that it seems straightforward and does not have unnecessary fillers. The transition from childhood to teens did not take too much time,... more>> but still, it did not feel like it's lacking foundation or background for why Liel turned out to be a yandere for Lucy.

Although I am still quite curious why Liel opened up immediately to Lucy. Was it really just because they are of the same age and she asked to be his friend? And did he fall for her at first sight or was it somehow gradually--how she takes care of him on an almost daily basis? And has he been acting like a crybaby just so he can stick to Lucy more?


I also appreciate the fact that we get to read it on 3 different povs. So you don't have to keep on guessing their level of understanding with one another. It's less frustrating for readers when one character acts a certain way and the other cannot seem to grasp it.

Enjoying this for now. Thank you~ <<less

The translation is good but the story itself feels very basic. Due to how dense the protagonist is, she doesn't see how infatuated ML is with her. Also, because the protagonist knows she reincarnated into a book and knows the male lead is a yandere, she tries to separate herself from him which causes a bunch of misunderstandings. I've already read novels like this before... It's readable but overall uninteresting.
