He’s probably into you and your friend. It’s normal but it’s also risky to go to a guy’s place who you just met, because while he’s probably just a normal dude and it’ll probably be fine, there’s always the risk that he could have malicious intent and you’re going somewhere with him away from public view. I guess the fact that your friend would be with you makes it a little bit safer, if you think worst case scenario the two of you could overpower him.
