Still his suspicion is non-valid and base-less, there is no need for him to think that way at all, when seeing two guys hanging out together - being a guy especially- the first thing to come to mind isn’t ‘ oh they’re gay’,
Also when he shit-talked about the bottom in front of alex and alex ignored him, so he started thinking that they must be hiding something isn’t realistic. I mean imagine someone shit-talked ur friend infront of you and they dont know that ur friends and u dont want to cause trouble: you ignore what they said and walk away to never deal with the asshole again. Which is exactly what alex looked like he did, so this whole development is illogical and RIDCULOUS
This is kinda ridiculous from the author, i mean, they didn’t do anything in public and the story is very logical in a way that ‘they’re totally in secret’, this guy going around and making assumptions is not at all a natural story flow, its like the author came and planted him there for drama, I hate it when authors do this , I mean you’re creative enough to write a story, I don’t think a simple ‘public accident’ will be too much to write just to make this asshole nosey character seem plausible(╯°Д °)╯╧╧
