The manhwa is doing a very poor job in reflecting mc's inner monologues, he mentions in the novel how he is very in love with the ml to the point he is willing to have no intimate relationships with him and settle for small kisses and cuddles instead, he also says that even if ml were to reject him after mc's confession, he had no plans of cutting ties with ml and was just going to settle for being close friends.
The mc is not THAT miserable tbh, he loves ml tooooo much like he is willing to accept anything as long as he can be with ml and he views their relationship as more of a torture for the ml than himself. (ml has a trauma related to male betas which is why the thought of being intimate with one makes him physically sick. .) Mc however is really into ml's looks (duh) so them not being intimate does hurt him sometimes. .but he keeps telling himself that even this much is enough for him and he shouldn't be too greedy.
Even their break up was initiated by the ml cause the ml thought he cheated on mc with an omega (the omega was mc) even tho ml was actually drugged at that time so yeah. .

I was looking at the raws, can someone who read the novel tell me why the heck the MC didn't break up with the ML? He just looks miserable in the relationship
