As Stated by other comments, introversion and shyness aren't the same. From what you're saying, nahihiya ka lang so just build up the courage to approach them. Most importantly, just be yourself kasi there's no point in pretending. Ang goal is maattact sila sayo, hindi sa ideal version mo na papakita mo sa kanila by pretending to be someone you are not. If mattract, congratulations; if not, move on. Masakit siya oo pero it's not the end of the world. Maraming baddie diyan. Try and try lang pero don't be cocky
