What Is Love (2012)

If you liked A.C. there's a really good chance you will like What is Love. They are both extremely romantic dramas about a jerky rich playboy who starts out playing games with the female lead, only to fall in love with her. Also Chris Wu gets bumped up from second male lead in A.C.to male lead in W.i.L.

-Non conventional premise
-One of those women-dramas
-The guy fell hard for the girl and proves his lover for her

Both dramas have Chris Wu as the lead and he is a producer of some form in both. Also the female lead of Rock 'n' Road was also in What is Love, but played a different character.

the male lead is a player at the beginning but he has mature conversations about relationship with the female lead.
