I MET THE MALE LEAD IN PRISON

I Met the Male Lead In Prison summary:

I met the male lead in the prison.
I know he's supposed to be a 19+ tragedy novel male lead, but...
Why is he like that?
"Woof! Woof! Woof! Grrr."
It was said that he was cursed to turn into a beast...
So, what is it like to awaken from the curse?
"T-T-Take responsibility, or d-don't touch me!"
I just felt relieved, thinking there wouldn't be any romantic feelings/involvement between me and the male lead.
"One year later. P-Please meet me... on the day I get out of here!"
Meeting him didn't seem too difficult, so I agreed.
So I was released first, but...
***
”Come on in. My lovely little sister who's as charming as the flower."
On the day I was released, the man who approached me turned out to be my brother.
I was the villain's siser.
"You went through a lot on my behalf, didn't you? I've been waiting for you."
…Fuck. On top of it all, I’m the precious little sister of the villain that is the male lead’s nemesis?
***
Three years later, when we met again, the male lead smiled with a completely different face.
"Hello, Iyana. I'm going to kidnap you from now on."
