He isn’t just “playing games”
He’s playing relationship RP with her, offline Risk of Rain, liked her picture on Twitter, picked up some of her mannerism (vice-versa) invited her to play with his boys and they made multiple remarks like “He‘s shy”, “95-5” and the continuous glazing they did.
It’s obvious for anyone who has actually interacted with women that these two are probably talking in the DMs at the very least.
It is parasocial behaviour but at the end of the day you’re in the wrong forums if you can’t handle some level of speculation and weirdness.
