This guy seems really calm and nonchalant about the fact that his 3D idol waifu who he loves more than anything suddenly shows up, is living in the same dorm as him, likes him more than anyone else, and wants him to call her by her first name.
It's called being an apathetic, dense anime MC. Not even watching this show but I'm guessing he hasn't made a move and never will.
He's too busy being a tsukkomi and creating his own jokes to have any kind of romantic development.
He's also too busy arguing with his childhood friend and discussing the finer points of fetishism with his glasses friend to ever do anything else
If nothing else, he's a hard worker
