~They were at first surprised that they had both fallen for the same person, because of their different personalities 

~Both of them try to make it fair game, but Tamaki always gets a little discouraged going ‘against’ Mirio

~It probably wouldn’t really affect their relationship that much, Tamaki might get a little discouraged for a while if Mirio ended up getting the girl, but it would wash over pretty soon

~Mirio tries to show off a bit, but doesn’t try to up show Tamaki. He actually tries to act like Tamaki’s wing man just to make sure that it’s fair game.
