Hey guysI need help finding what a manwha. I forgot what it was about but I remember that the main lead hated the mc because when they were younger the ml tried to confess his feeling for the mc, but the mc thought he was making fun of him for being gay and also thought he was annoying so the mc ended up locking the ml in a cage with a dog that the mc was supposed to get a key out of. So later in life ml tried to get revenge on the mc but I forgot if he tortures him or like just fucks him until he can’t any longer and that’s like the form of revenge lol . Anyways if anyone knows which manwha I’m talking about plz let me know. And also I think there in like a college setting if I’m not mistaken ٩(๑❛ᴗ❛๑)۶
