I'm redoing most chapters of the book. I will try to keep the former scenarios I put for the characters but some things will change slightly.

Sano:

Whenever you help him work out, which is rare, you will be sweating a lot and out of breath. So when you put your hands on your knees, trying to take your breath, Sano had a full view of your ass. He could immediatly feel his pants tighten so he just snatched your arm then dragged you to the showers to take care of you and his problem.

Nakatsu:

He gets it a lot but he is actually good at hiding it. He will just enter a room when your not looking and try to get rid of his problem fast. One time he entered the kitchen, wanting a snack and saw you licking your fingers clean so his pants tighten. Before you could even ask him why he's here, he already ran back out the room, annoyed mumbling under his breath about how pretty and sexy you looked.

Nanba:

This boy probably gets a boner by just looking at you. There was one time when he entered, wanting to give you your binder which you forgot in the classroom only to find you with only underwear on since you were changing into your pajamas. He just stared as you awkward told him he has a little problem in his pants. He awkward handed the binder then left your room, going to the bathroom to go take care of his problem in his pants.

Taiki:

He barely gets it since he isn't as dirty minded as everyone in the school but there was a time you and him were on a very busy bus so you sat on his lap. But with each bump, you shifted on his lap, rubbing against him. When the bus finally stopped at your stop, you could feel Taiki's erection. He was very embarrassed. You awkwardly apologized while hurrying to get off. Poor Taiki had to sit with his backpack on his lap, embarrassed and awkward.

Ashiya:

You wore the school white shirt. As you both talked, she accidenlty pushed you while she was avoiding some passing students so it caused you to fall in the river. When you were back up the surface, were angry with her. But when you scolded her and got no reaction, ask her what wrong is. Her eyes were too focused on your chest because the wet white shirt made your body visible. She apologized then ran away, embarrassed that you caught her staring at your body and she was now feeling turned on.
