i definitely saw this comment yesterday

Yes it’s called rainbow city (novel). Manhwa isn’t there yet but if you do decide to read it SA in chap 3, best to skip (ik it sounds bad but I promise it he established relationship is green) or if you don’t wanna read the thick story then I suggest the rainbow city novel but just the side stories so you can really feel it https://readhive.org/series/50056/
Night of London

scandalous wedding

I just finished reading all this, thank u so muchh!!

Youre welcome! You should also try Unsleep if you havent read it. The top is doting and attentive, and I wish he were mine (/TДT)/, and his obsession really shines in ch 19 which will come out here in a couple days:
