@rawon My Love Story is this:

My Love Story on Wikipedia

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.

Sounds fun, and modern day setting is something I haven't seen before in the otome isekai genre.

13 is too damn many (but I'd still give it a try).

I suspect the author wanted to write more but wasn't allowed to. Still, we got a proper closure for this series. I don't know if this is popular enough for JNC to consider licensing, especially with a completed fan translation, but one can always hope.
