Help , I don’t get it someone explain fast

1)kyungsoo let the other guy(already forgot his name) go so that he can leave a normal life
2)yule wasn't able to leave kyungsoo alone
3)kyungsoo has mixed feelings about yule...he doesnt believe that they can be happy but he doesnt have the strength to let him go either(he blames himself for everything/he hates him but at the same time he loves him).
the ending is kinda open and leaves it to the reader to decide whether or not yule and kyungsoo end up together.

He stopped seeing the nice guy, and lives on his own now. Yule has been watching him, and most likely they will get back together, hopefully into a more healthy relationship. (⌒▽⌒)

Thanks (づ￣ ³￣)づ
