author said sangwoo never loved bum, sangwoo was hetero and he just let him stay cause he looks like his mom so NO its so frustrating it could end better its so unrealistic and its just exist to mess your mind up >:/ i hate it

Yes, in fact she did say that. Go back and read the author's replies to questions that were asked.
Well I think they fulfilled their promise to each other at the ending. Cause when they were talking about death Sangwoon said if he dies first, Bum should try to die as well, either it was hanging himself or etc. Yeahhh, until the end they had each other. I like the story very much, well done.
