Okay so there's this guy I've been talking to and I thought we were only just フレンズ and he thinks we're in a relationship. I've told him I don't want to be in a relationship but he keeps pushing.

:O omg, this is serious! i don't like this guy, he doesn't seem like a friend to me, okay be stern with him and don't try to sound playful about it! tell him あなた REALLY don't like it and make sure there are other people around and you're not alone, if he still doesn't get the message then tell your フレンズ または somebody (bodies) あなた can trust about him so that they can look out for you, and if あなた are still scared then, this is going to sound corny but tell a trusted adult, they should be able to handle your situation until it is resolved

OMG!!! well if he stalks u try to be near an adult tat u kno and maybe tell them what that guy telling u nd doing to u and also tell him to leave u alone
