Sweet/Adorable Male Leads

Hello! I absolutely love watching dramas with sweet and adorable male leads. They don't need to be in the beginning, however. I've seen several slap and kiss dramas where they don't start acting sweet to the female lead until later, so either is fine with me. 

Examples of what I'm wanting are:

Bpoop Phaeh Saniwaat

Kleun Cheewit
