SW-363 Invited girls from class to come home and play, the boys killed them one by one

The summary is roughly the same as the movie's title (Inviting a girl from class to his house to play, the male student "kills" them one by one), there is a part where the young man invites the female student in the dormitory next door to his room. "chat". In general, these college students are very lewd, they actively show their asses to the guys, the guys just "kill" them one by one.
