You and Tamaki were close friends, it wasn't anything special. Just friends. At least that what you both thought. It was pretty obvious to everyone else, but you two, that you guys liked each other. But you both were too damn shy to admit it.
He was super shy, always wanted to go home, his hobby's were; just sorta tagging along, following everyone else, he didn't really want to be a leader.

And it was pretty flipping obvious on who it was about. Nejire heard you from out side your dorm, she told Mirio then they both went to Tamaki. They told him that you wanted to talk to him and that you were up in your dorm. So he listened and went up to your dorm, knocked a couple times, no answer, but he could hear something from inside...
