I'm looking for dramas where main characters are best friends (and maybe female one have a crush on her male friend?) and in the end they fall in love with each other. Any sugestions, ideas, something? 

Pinocchio (2014) - childhood friends / adopted family 
Weightlifting Fairy Kim Bok Joo (2016) - childhood friends reunited
Weighlifting fairy Kim Bok Joo is gorgerous, i've just ended watching this today :-)
