I need help finding the title

I know the actors faces but I can't remember the titles... 

It was a school setting with guy falling in love with his best buddy while gay guy got problems at school (usual white and blue track suits like in Heroin). Both get to hugging or one shared kiss, not sure, but not gay guy doesn't follow up and chooses hetero lifestyle while gay guy founds a BL production company after graduating. Then they meet again at not gay guy's wedding where gay guy sings a heart-breaking song (kinda remembering their school days and at the same time saying goodbye).
There is a continuation with a gay couple breaking up cause one of them has to marry and them getting quasi wedding photos done of the two of them before that one guy is off to marry.

Can someone please help out? Thx! :)

China, I think.
