Sorry. I've read it, but I can't remember it. I remember that he's, like, top of the class and the teacher is asking him to tutor her or she going to fail. He's not thrilled but turning down a teacher would blow his image, so he agrees but I think he's telling her she's going the regret it and he's not going to go easy on her. Think she finds out he's actually a delinquent sort when he's not in school, but it's been awhile.
I really wish they would identify the manga they take their 'ad' pages from just to show proper courtesy to the artist. You should ALWAYS give credit when you use another's work in your own, whether it's a quote or art. That honoring copywright too.
I found the mangaka's name :) It is SAIJOU Ayano. Maybe having that will help find the mangas name. I had remembered seeing similar drawings and found the manga for it. Hope that helps if you are still looking :)
