Romance books that makes your heart feel warm and fuzzy.

Hi guys!

I love sad af books and beautiful writings and whatnot but when it comes to romance, my mind goes blank because literally EVERYONE raves about romances like The hating game, The kiss quotient, Get a life chloe brown, etc. and I have no idea at all. As a beginner to this genre, please suggest me some sweet romance that you have loved. Thank you!
