If a guy lets me in his personal space?

[Anonymous]

I've been hanging out with this shy/sarcastic guy (he's not really a people's person). He has a great humor and is super smart. Today for the first time we hung out as his room and he said he doesn't really let people in his room. And then I said that I felt bad because I suggested that we hangout there and he said "no if I minded you coming I wouldn't have let you in".
we also had multiple moments when we looked at each other and then he smiled. when I asked why he kept on saying "nothing". and then he was like "I just find our friendship unique"
