@rawon My Love Story is this:
It's the story of Gouda Takeo, a 1st-year High School student who's so big everyone thinks he's in college, and his girlfriend... who he met in a fashion similar to how Momo met Hime in "Are You OK With A Slightly Older Girlfriend". Like, the only difference is that instead of implying the guy was groping a man, Gouda grabbed the guy's hand and wound up getting suspended for punching the guy after he said the girl deserved it... while in the presence of a police officer. It's the story of their relationship, and I first learned of it through the anime.
So now I've got three series I've got to purchase through Viz I guess, since Wikipedia says Viz has the manga license.
