So basically he was born an extrovert but forced to be introvert?

wow. can't relate

I can cultural stereotypes and whatnot, girls have to be lady like, be seen and not heard, don't smile too much, don't laugh too loud, sit properly, hold yourself with grace etcetera kinda sucks so I use the Internet as an outlet to be as silly as I like

Why this reminds me of etiquette like those manhwa

felt

It is kinda like that but you get downgraded if you don't exercise it properly like this one time it was my cousin's birthday party and my older cousin came over to talk to me, and istg if looks could kill, my mother and father would've murdered me twofold
