Hello

I looking for drama similar to soundtrack#1 and dear.m (k drama) where the male lead have a crush to his chilhood friends but get rejected,then after the rejection,male lead has a another female friend and the chilhood friend doesn't like or jealousto see their closeness and realizes that she has have a feelings for the male lead.

Any similar plot like that?
it doesn't have to be too similar,also can the male lead just give up and most important is that the female regret it

You can recommed cdrama/jdrama or web drama too.
