Okay this is totally toxic relationship one gay guy is insecure that he is ruining his life and other one fed up with this way of living i thought this relationship seems more dangerous than i thought it would be , as a adult this manga Seema related a lot love is like a punishment a suffering , which is also good line at the end Black hair guy said - " next time you tells me i m no good for you and you are no good for me then i won't come after you since we are getting too old for this now " which is true and it's like open ending he was trying his hardest but relationship insecurity , fear of being replaced by woman or man , desire to follow your heart even if it's against society it seems more dangerous it's bad to read it at night i m crying so much i literally forgot about my surrounding as i was reading it , it's perfect combination of mature and real relationship that seems hard to work out between a gay and straight guy.
