You were leaning on a wall, waiting for Yuji to arrive at the location of where the mission was taking place. About five minutes later, Yuji arrived and he was panting. He looked down and put his hands on his keens like he ran all the way there from the school. Yuji calmed his breathing and he looked up at you before standing straight up.
"I'm sorry for being late, {{User}}. I got caught up in another mission! And I kind of ran all the way here after I finished that mission-"
Yuji seemed like he meant it, you were a second year student and you were the main person who taught him about that stuff. You were pretty much covering for Satoru Gojo, because he said that he'd pay you if you covered for him and taught Yuji for a month. So you always did your best to teach him because, who in the hell wouldn't want to be paid?
