I Met the Male Lead in Prison

I met the male lead in prison. Okay. I get that I transmigrated into an R-19 tragic romantic novel, but why is he like that? ''Bark! Bark! Bark! Grrrrrr...'' I can't believe this guy is held by a curse that makes him act like a beast ... And that's not the end of it, because when he returns to normal for a moment. ''I-i-if you aren't g-going to take responsibility for what you did to me, th-th-then don't touch me!'' At any rate, I felt relieved that I probably wouldn't have any sorts of romantic interaction with this guy. '' 1 year ago. Th-th-the day I leave this place, please...m-meet up with me!'' Well it, wouldn't be a big deal to meet him once. But, then, when I was released from prison...*** Welcome back. My lovely younger sister.'' The day of my release, a man approached me. Turns out, I am the villain's sister. ''You must have suffered going to prison in my stead. I waited only for you''... F*ck. My brother's the male lead's sworn enemy?***3 years later, I meet the male lead. He looked totally different than when I last saw him. ''It's been a while, Lana. I am going to kidnap you now.''
