I'm a big fan of when a mc wins over the affection of their love interest after that love interest has been in love with someone else. I'm also a fan of when the childhood friend wins.

So male mc who likes female lead who likes someone else at first and then realizes her feelings for male mc.

There's the first story from Kimi no Kiss de Me o Samasu that I can remember at the moment.

Okay, I managed to remember two others:
Tonari no Atashi and Shishunki Bitter Change (although it hasn't been confirmed yet, this is the route I think it will go).

Shishunki no Iron Maiden maybe
