I feel like I read a manga with one family that's really wealthy and they ruined/betrayed another family and they both have kids around the same age who meet in high school.

The wealthy ones have a girl and the bankrupt ones have a boy and I think there's this scene when they're both pretty young and the boy is looking into the gardern where the girl is being all happy and stuff and the boy gets all jealous of how happy and perfect her life is or something.

I think he initially date her out of revenge and then falls in love, but the parents don't agree so I think he kidnaps/runs away her and takes her to one of his hangouts where she learns to live like a commoner for a bit (I think she gets re-kidnapped by her family pretty quickly, though) and she sucks at being poor, since she can't even blow-dry her own hair and makes the guy do it. I remember another scene where she's wearing his shirt at the hangout (this is still when they've run away together and are hiding out there) because she has nothing else to wear and then at some point she goes out to buy food (at a restaurant or fast food place, I can't recall which) but has no money.

Then again, the runaway one and the looking into the garden one might have been two completely different manga XD I feel like I remember the characters looking like Wann's, but I checked all of her works and it's not one of hers, so don't base it off that. I think it was a manhwa, but I could be wrong. If anyone has any idea of what I'm talking about, feel free to take a guess, I suppose? XD

its probably Royal Seventeen

Lol, that was fast. I'm pretty sure that's it, though I can't find it on any online readers so I'll have to download it to check for sure, but I think you're right. Thanks John

EDIT: Yep, you're a genius John. And I no wonder I couldn't find it, it wasn't on my lists XD
