I want to learn German!

Hello. I'm living in Berlin and want to learn Deutsch. also making good friends too. I am from South Korea and speak in English a little bit but poor haha. my Deutsch level is B2 in school but i think it is just title. my language is unfortunately bad. so I need any friends for talking,  because I love to talk but I can't speak enough here. so I feel heavy in my heart. I am not crazy or pervert. I am just a normal person.
if someone want to be friend with me and help me, please, tell me. oh, and I can teach you Korean if you want.
bye~
