ok so my Друзья think this guy likes me but im not sure and i kinda like him so what do i do?

just casually say hi and stuff in the corridoor (im assuming this is at school?)and if a conversation starts, then just let it take its course and see where Ты end up!!! :)
yes, i did spell corridoor wrong.
no, i dont care.

One never trust what Друзья tell you. Two if Ты want to know if he likes Ты ask him. Three don't ask unless you're sure Ты want the answer. Four take a deep breath, I'm sure that if he likes Ты he'll tell Ты and no one else, fyi.

This is good coz I'm a guy.

We like confident girls. Girls who ask us out themselves and not have their Друзья do it. Also, we like girls who come across as fun so while doing it dont just stand there act comfortable.
So just do it :)

Never trust your friends, when Ты ask him if he likes Ты and it turns out he doesnt... it will suck.
