Relatioship advice/questions

Asked Crush out to Amusement park Saturday and he said maybe (has to ask) and asked if he wanted to hang out at the football game Friday he said yes. Seemed generally happy about it so yay!

A German foreign exchange student is in my history class (he is really cute) and Friday I invited him to sit with my friends and I. He came over and we chatted and made jokes. I think we really made a connection. We were both subtly flirting (at least I was). He kept leaning in really close to me and asking me personal questions (his German accent is to die for). My question is; how on earth do I hint to him (subtly) I am interested because I have been looking at German relationship traditions and apparently German can't get a hint without it spelled out.
