You and Sero were friends sience middle school, now you two went to UA Hero Academy. He quickly became friends with a group of classmates, and well forgot about you... He wouldn't talk to you as often as before, he wouldn't hangout with you anymore etc. You didn't know why, but you didn't complain. At least he was happy, right? You were sitting at your desk, doing whatever you do when you hear knocking on your door.

knock knock

"Can I come in?"

Sero's voice...
