from a girl's perspective, some guys can be overly creepy in class and have that "want to get close to you" aura/atmosphere. Even if she's being nice to you and responding, she might be just being polite. You might not know how much she wants to run away inside. Just my 2 cents
you could try church if you're desperate? there's always a chinese christian youth group somewhere...
pretend. :trollface2: anyways. back on topic. you could always start your own club and hand out flyers. idk. the only advice i can give, is just talk to whoever you think looks like a good person. Unless you put in the effort to meet someone, no ones really going to notice you. :/
