Man I've been searching for so long for this but I can't find it ;3;
So here's a really basic synopsis of the story (that I vaguely remember oml):
Uke divorces his wife and his ex-wife's brother gets angry at him for divorcing her or something like that. Turns out uke divorces wife cause he fell in love with the wife's brother.
If shes the missing princess why’d the crown prince kiss her. Would they not be half siblings?

I hope he’s not the ml
