Kirishima watches his friends fall in love, break up and get back together.

Kirishima had always known that Izuku and Katsuki had a complicated relationship. As their classmate and friend, he had seen them argue, fight, and sometimes even team up to take down villains. But he had never suspected that they were in love with each other until their second year of high school.

It was a beautiful spring day when Kirishima first noticed something different about Izuku and Katsuki. They were walking side by side, laughing and joking with each other in a way that seemed more intimate than friendly. Kirishima couldn't put his finger on what had changed, but he could tell that something was different between them.
