Palok's manga / #heart broken(2)

A gets drunk after attending the wedding of the person he used to love and gets drunk outside of a restaurant that has the same name as his friend. He is taken care of by a highschooler who has the same family name as his friend who eventually helps him work through his unrequited love for his high school friend, which had actually been requited, but that A had rejected the possibility of a relationship- hate regret stories...he made his friend and himself suffer, if he could not handle it he should not have said anything is what I think

A liked Sensei, but was warned to stay away, very vaguely by B (legit he should have just said, hey I am involved with Sensei, and he is only in it for sex so...) A is shown Sensei and B having sex, heartbroken. Sensei is a dick. Die. Ryou moves to the school, announces he is gay, he takes interest in A whose friends were concerned, eventually they realise they get on and Ryou confesses to A, who eventually after coming accross Sensei and B making out, and then B getting turned away by Sensei and then Sensei propositioning Ryou, A realises he also likes B and goes and confesses, had said words of encouragement to B who goes and tells his true feelings to Sensei, in the end everyone is happy. I personally do not like Sensei, I feel like from the face he made when A saw them having sex there are some things people turn into that they cannot genuinely come back from but then i suppose we all impose restrictions and impositions upon our selves in our daily lives to not defy social codes...
