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
