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, with 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 imprisoned 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.

Although her denseness is annoying, the story is cute and also has that air of mystery that can keep you running through the whole thing. The ML appropriately understands and accepts his own feelings as he also patiently deals with someone unable to understand her own feelings let alone another person. It also explains that the ML liked the FL since before the story, the reason the original includes her own death was because she was arrogant then and treated the ML like sh*t (Our FL was endlessly kind... more>> and considerate to him). Showing she changed the story from her birth. His feelings for her are only obvious to others, who have eperienced his actual self and she only knows his kind facade that he's kept from their first meeting. Or maybe he is kind and pretends to be cold to everyone else. But that is unbelievable.

It also explains the reason the ML is a yandere (or just largely obsessive and possessive).

He learnt love from the Duke, who was practically obsessed with the ML's mother. And he eventually learnt that true love is when you don't give up and go to extreme methods to have the other person, even if their love for you is fake.


Update: The twists are amazing cause, I love the way they didn't make the ML half demon and he was a normal child until

the FL saved him and turned him into her bowl.


This is a big spoiler and basically a summary of the recent chapters I've read. Read at your own risk.


The FL was actually an angel that was ordered by the Goddess Ophelia to become the Demon King so she could stop the demons from going too far. The deeper reason for this part is because the Goddess had to turn time back multiple times since humans kept slaughtering each other, and when the Goddess made the demons to create a common enemy, the demons couldn't hold back and ended up slaughtering the humans. The Goddess sent FL to become the new DK and rule better, a few years later or so, Baal (previous DK) came and ripped off the FL's leg. He wanted to be the DK again and he also wanted revenge on the FL. The FL survived and saved the ML by placing her power in him, then later decided ro rebirth herself as Lucy. Eventually meeting the ML and falling in love with him.

Okay, I love this and I can't list up all the reasons, I was looking for a novel like this for a while, the story ain't cringy and the FL and ML have this sweet and cute lovey-dovey relationship (one-sided for now) and it's really funny that the FL Lucy keeps being clueless about everything even when there's a hint of love for him in her that she kinda denies and idk but I've got a feeling that ML kinda gets it with the imprisonment, their childhood is cute and... more>> not too long and the story is filled with sweet moments of them since childhood and in the meantime it explains all prospectives without leaving the reader with confusion and caos just like at the final ch they show u the ML confession and the apologizing for sh!t of ages ago hehe = ̄ω ̄=

Okay it's amusing for me ppl and I swear it ain't cringy and stuff, WARNING:Only for people into cutie FL and ML with strong hearts so that they can survive cuteness ^0^ <<less
