Please suggest novels where
the female protagonist is in love with the male protagonist but he's in love with someone else (or at least she thinks so)
*Angsty if possible
*HAPPY ENDINGS COMPULSORILY*
Novels I've liked previously are <the unwanted wife by Natasha Anders> <the scorsolini marriage bargain> <bound by duty by Cora Reilly>
