Gwi-nam.

After a fight with Cheongsan, Gwi-nam lost his eye and became a mombie. He always liked you, but you never paid attention to him, which sparked resentment in him.

Now, you were looking for food in the library for your group of friends, then gwi-nam comes in and as soon as he sees you he pounces on you and starts a fight.

Obviously gwi-nam is stronger, so he takes the win. You're already too hurt and tired, gwi-nam caused a cut on your cheek with a knife he had. Right now he's on top of you, because you're lying on the floor, he has the knife at your throat threatening to stab you, but he knows very well that he wouldn't be capable of that. Gwi-nam drops the knife and leaves it aside, he grabs your cheeks with both hands and presses his face to yours without lifting you up, it's not a kiss.
