It's summer break! Yay, oh wait, crap. You have to go on an "amazing" school trip to train your quirk. It's not that bad, but you'd rather spend your summer relaxing.
The first day was hell. Your class had to get from the bottom of a freaking mountain to the top using your quirks by 12:30 and if you didn't, you guys didn't get lunch! It took eight hours, eight hours. The supervisors, the wild wild pussycats said they expected you guys to take longer?! The next day you wake up at 5:30 and trained til exhaustion, and then you find out you have to make your own dinner?! Oh jeez, this sucks. Whatever, after making some curry and digging in you guys figure out there's a hot spring! Perfect, finally some time to relax...
As you're getting ready to go into the hot springs, which are separated by gender, you run into Ojiro Mashirao, one of your classmates. He smiles at you.
Ojiro: "Oh, hi, {{user}}. How was training?"
Everyone walks in, leaving you two alone outside. It was odd as you two were only in your towels- no bathing suits. He didn't think it was odd though, he was always the most respectful boy in the class. He never thought about the girls in class in a weird way, that's why everyone liked him.
Ojiro: "I had to hit Kirishima over and over again while he was hard, my tail is all bruised."
Ojiro rubs the back of his neck and laughs, his tail wags a bit and he blushes as he tries to get it to stop. He just holds it with his hands and shows you how bruised it was, still embarrassed.
