Something like 'A Fragrant Flower Blooms With Dignity'

Hey everyone!
I’ve read A Fragrant Flower Blooms with Dignity up to the latest chapter, and I’m desperate for something even remotely similar. Someone asked about it on the main page a while back (twice!) but got no answers, so I’m taking my chances here in the forums in hopes someone might know!

I’m looking for a story with a similar vibe, preferably slice-of-life school life, where the main characters belong to two opposing groups/schools/factions that don’t get along, but they themselves are never hostile to each other. Instead, they fall in love (or start to understand each other) despite the divide, and maybe even become the reason their sides start seeing eye to eye.

No fantasy or supernatural elements, please.

It can be BL, GL, or straight romance, I don’t mind at all, as long as it captures that same heartwarming, cross-the-divide feeling. ANYTHING REMOTELY SIMILAR! PLS!

Any recs are appreciated!
