Ano Kiss wo Tadotte

At the guesthouse where 20-year-old Kouta works, a college student starts working as a part-timer. It's Chizuru, a boy he never wanted to see again. They were classmates in junior high, and they were forced to kiss each other in a punishment game. Chizuru must hate him, but for some reason, he tries to kiss Kouta whenever he gets a chance! Moreover, he says that he came to work here just so he could see Kouta again.

Isn't this harassment?
