Heart Stain

U Hyeon has feelings for his homeroom teacher and intends to keep this hidden until graduation. However, when his best friend, Do Ha, finds out, U Hyeon fears Do Ha will judge him for liking men.

Surprisingly, Do Ha responds with an unexpected proposal—to date each other until graduation—and so, U Hyeon, wanting to give up his feelings for the teacher, agrees to Do Ha’s suggestion.
