Yeah....
It's teacher (uke, weak looking), and student (seme, much younger, looks like a little boy, with mean eyes, domineering, rich or a yakuza or something). The kid forces the teacher (there was one scene in the nurse's office), the teacher is reluctant (likes it but doesn't know that yet). Later, the kid's guardian (pretty looking man) shows up, wants to separate the teacher from the kid. Kid's dad shows up (dad seems to like the guardian), and somehow, for some reason, dad tries to sleep with the teacher (teacher visits the kid's house), kid shows up and says to everybody that he likes the teacher.

Thank you so much, guys. My brain's gonna explode.
