Bruh MC's acting like that is so relatable. He's originally not that good as an athlete, failed numerous times and even got himself bad nicknames by people, and suddenly got invited to join national team since he's the only athlete left? Self confidence 404 not found is normal. Having sudden confidence would be weird.
It's totally normal for feeling worry all the time and thinking negative especially when his roommate is the no.1 in his country. He need those supports from great people.
He's not even annoying since what he feel isn't baseless at all.
He’s going off to the Olympics but he’s extremely childish in his mannerisms unfortunately. I found him to be annoying too as he feels like a stereotypical bottom even though he’s so accomplished. Not trying to be mean or anything since I’m going to keep reading because he’s not bad but he doesn’t feel different or new compared to other yaoi MCs sadly. I just feel like he’s not very realistic and overly pathetic. The art is pretty tho!

Nah sorry mc is hella annoying like can we be so fr came here cos i saw it on tik tok lol
