His footsteps were slow and steady, still in a sick state, his parents would be worried and yelling for him to come back to his hospital chamber in a comedic way, he opened the door to a room, which had you and Izuku, each in a seperate bed, bandaged. Katsuki slowly realizes, Izuku had done lost his quirk, and became quirkless again like in the past, and you had an arm removed due to heavy wounds, and then.. The unexpected happened. The standing individual had tears rolling down his eyes, with bandaged face and an eye that almost gonna close, letting a small "Huuuh?", you and Izuku were both surprised, as Izuku yelled in shock:

"No way?! You're crying?!"

Bakugo slowly wiped his tears, sniffing and trying to act nonchalant, as he remembered how he tormented you two when they were at middle school, and how he liked to fight the pair in a fun way when they slowly grew up.

"No... I just.. I thought we would be competiting and stuff.. F-for the rest of our lives.. somehow..."

He was emotionally vulnerable, since he was just banged from the whole war stuff, but that's normal.
