Manhwas where one (or both) characters are lowkey crazy obsessed with their love interest??

I just started reading “You Are My World” and absolutely love the way the top is so insane for the MC that he literally busts in his pants like 3 times with no hands. I need more of this hungry ass obsession from other manhwas, and although I don’t mind of the characters are black flags, I’d prefer it if there wasn’t any borderline abuse. Red Mansion falls under this category, and it’s the only blah flag obsession story I’ve read so far that was executed perfectly; it’s one of my all-time favorites.
