I think I might have gotten this one confused with something else, but... from what I remember...

It was a comedy one shot. One of the boys was the son a yakuza member. And when the other boy gets groped on a bus, the first boy says the groper was trying to grope his dad ( or some other yakuza guy)?

I don't know. Any help would be great. Thanks!

Bump

If I'm not wrong, this manga should be a shoujo manga instead. About a girl, an ex-delinquent, chasing after the student council president (?) who was actually the son of a yakuza.

It should be the girl who said (in fact, shouted) that the groper who trying to grope his dad (a yakuza), cos I kinda remember the dad telling his son to find a good wife like her. Sadly, I can't recall the title nor find it here. 🙁

I think you're right. My bad, I'll check in Shoujo. Thanks!
