Whats the best way to approach a girl?

I'm not a club kind of guy. so, that option already crossed out for me. 🙂

I go to a gym, but only girls coming are with there boyfriends or either they are too big for me (by age obviously 😅).

Also don't know why but looks like my company only hires boys in tech. so, no luck out there too. 🥲🥲

Tried dating apps but no luck there. hardly getting any matches. 🥲🥲

Where should I go next?? I'm mere 23, earns desent (~1.5L a month), totally introvert so, don't know how to talk to a girl much.

All I'm searching is a simple sweet girl. where Can I find those girls in bangalore??
