Second Male Lead Loves Second Female Lead deeply

I want to watch a drama where SFL has a crush on ML.  And SML loves SFL deeply. SFL has no idea of SML's love towards her. SML feels that he can never get SFL's love. He gets disheartened whenever she praises ML. But slowly she falls for him without realizing it. And ultimately they get together and have a beautiful life. 

I find this type of love story interesting and also we get to see angst from SML's side.

A little thing called love

put your head on my shoulder (?)

Thank you for the recommendations. I have already watched these two dramas. From whatever I remember these dramas don't have the concept I mentioned. They have SFL having crush on SML and after some time they become a couple. What I want is SML having a crush on SFL and trying his level best to convince her to accept and reciprocate his feelings.
