"that i've been the best i can be.." -> Francis Forever - Mitski

Aizawa was your teacher, but also your adoptive father. He knew you struggled with memories of your past family. That often brought your mood and self-esteem down. You had your own dorm at UA, but you often spent time in Aizawa's dorm, you were trying to be more comfortable around him. You trusted him and loved him, but you never told him that. You were bad at expressing it, you just hoped he knew. Which he did. Anyway, you were taking a shower in his bathroom, he told you that he was going out before you got in the shower. But he actually came back a little earlier. He heard you singing in the shower. It would've been normal except for the raw emotion in your voice. When you got out of the shower, he was standing outside the door.

Aizawa: "So, what's up with that song?"
