First, if the protagonist has no issues there's no story, and while i agree this shit is annoying, typical virgin personality, you don't get to tell how someone should or shouldn't act or think, it's common empathy my dude.Oh no shit, I didn't know that /s as someone that was naturally reserved as a teenager this is pushed to the extreme to an annoying extent and feels less believable because this guy 20+ years old. No normal person goes to far extremes like "s-she's hanging out with me, I-Im scared people might think we're a thing" just for being in close proximity within a girl. And if you or someone you know acts like that at your grown age then that's just embarrassing
Second, you're literally ranting to a drawing, get serious bro, go touch some grass if you're so good at telling someone that what he is doing is embarrassing
