I agree with you on I do feel like Saikawa has every right to be angry and jealous but I feel like he should explain it better because Sayama really doesn't understand those things. He was always alone and never talked. Not only that but Sayama said he didn't like it when the other guy bothered him but he wasn't going to leave him in the hall that way.

yeah, he should definitely communicate it better... i suppose to him, the situation feels like such a glaring, obvious issue, and he hopes sayama would realize on his own how bad it's making saikawa feel. teenagers (and many adults) are pretty bad at communicating well in a relationship in a proper way, especially if you're worried about accidentally hurting the other person by bringing your "negative" feelings (jealousy) to light

At this point people down here really need to understand from ALLL of the characters' pov. Like what would you do if your bf gets along w that one student known as stealing others lovers, what would you do if you noticed how that one student known as stealing lovers have his own side of story, what would you do if people misunderstand you and spread negative rumors about you. I might as well pity the mangaka for their readers picking sides demn it. I can tell from the mangaka's plot writing how they cherish all of their characters, but here the people already picking favorites-

i don't think picking favorites is a bad thing, nor does it mean people think the mangaka has done a bad job. i haven't seen anyone say they're annoyed that the mangaka decided to make the story this way or insinuate that the plot or characters are bad. flawed characters are good and the reason people are upset is because they have grown to love these characters and they want to see them succeed, and a roadblock is gonna have the readers feeling upset alongside the characters. for example, i hate malfoy in harry potter because he's an annoying prick, but does that mean i think he's a bad characters? not at all. disliking a character for the role they play in the story is not the same as disliking the story itself.

It's not, which is why it's worth to try. This is the same case as encountering conflicts IRL, not everyone can and want to understand all parties involved, but like I said, try eh? :D Other than that, I agree that it's okay to have favorites and should accept the wrongs their character does at the same time•^•
i dunno why so many people are mad at saikawa for being jealous, like... tsuguru is known throughout school to be a homewrecker and stealing other people's partners. sure, we just found out it's not actually like that, but saikawa has no idea about that, so from his perspective, there's a "mr-steal-yo-mans" getting all buddy buddy with his boyfriend, who seems to have no problems with this stranger flirting with him, and that's gotta feel pretty shitty if you ask me
as for avoiding sayama... i get it. jealousy is not a nice feeling to have, but you don't just make it go away (especially if you're high school age). saikawa doesn't wanna constantly have to watch his boyfriend be close with a homewrecker, because a) that would feel like crap, and b) it might make saikawa say something bad and hurt sayama's feelings. that's why he says he avoids sayama because he loves him; he doesn't wanna hurt sayama, and he wants to protect himself from his own jealousy
