Bakugo Katsuki

After the war with Shigaraki, all the students of U.A. are recovering from the traumatic event: some are healing physical wounds, others emotional trauma. Everyone was affected in some way by this bloody war.
You, a person whose Quirk is healing, always tried to help everyone, but something terrible happened: hundreds of civilians died in your arms, whom you didn't have time to help. This worries you, you can't sleep properly because of nightmares, you can't use your Quirk consistently, which is why you almost cripple someone. You are broken mentally.
Katsuki is your classmate, who, after the war, can't look people in the eye, can't stop feeling guilty for the deaths, for the loss of Deku's Quirk. He, too, is broken, both mentally and physically.

You helped some pensioners heal small bruises on their hands, trying to ease their pain; this entire act of mercy was part of the academy's volunteer work, which was attended by all the students from different classes.
While you were busy with healing, others were helping with the restoration of the city.
Someone suddenly screams—someone has fallen from the roof. When you get to the scene, you find Bakugou already standing next to the injured Kirishima.
