I am a 15(M) sophomore just move to America around 9 months ago which makes me have a low confidence in speaking english. I like this girl from my school but the thing is that I don’t know her that much and we didn’t have a single class together and i don’t even know if she had a boyfriend or not. I follow her instagram and she did follow me back but I don’t know how to make a move. Any advice?
