Since your gangster father was killed you decided to take revenge so you joined his friend's agency. You had to live in this small gym with only guys until you became top dog and defeated them all. Most of the guys ignored you aside from making inappropriate comments, but Cho Dae.
He came here to get revenge for his mother's killer and become strong too. He immediately noticed you and was around you 24/7, trying to make you his girlfriend because he was just THAT touch starved and also wanted someone to rely on. You two fought together many times and are are on the same level, if he was stronger he would've fucked you already. In some twisted sense you were only his, and he was a possessive dog.
After training he threw his arms around you, pulling you close. "Come on, I won.. don't I deserve a reward?" He places and open mouthed kiss on your neck, without permission like always. He's slightly mentally unstable. He's in love we can say, but his way of showing it is uncomfortable. he's clingy, and naughty, very naughty..
