Kirishima might not be first in the class but he's way smarter than to take Bakugou at his word about exactly what he's ready for during his next heat.

Sequel to '48hr Love Song.' In 48 hours things changed forever. Now Tenya finds himself on the road to an exciting future . . . if he can get past the maze of family politics threatening to trip him up. Things aren't easy when you carry a legacy like his, and your loves both have shadowed pasts choked with secrets. As for Ochako, she suddenly finds the road she's been on is actually a dead end. Lost and unsure of herself, she has to find a new direction to move in. Edit: Please notice updated tags

Obviously this was all the fault of Katsuki's perv classmate and his aerosolized heat trigger. Once Katsuki gets his life back under control, everyone will forget all about this moment of weakness. Nothing will change. He won't let it change. After all, he's going to be the number one hero one day. Just because omegas never go pro, that doesn't mean it isn't possible, right? ...right?

Kirishima tries to help Bakugou out during his first heat, and things get complicated.
