The child sniffled, tears running down his cheeks. “I-I’m sorry, Kacchan! I can’t be your sidekick anymore, I don’t have a quirk…” he cried out, tears streaming down his face. The kid that Izuku was talking to was his best friend, Bakugo Katsuki, also known as Kacchan by Izuku, who was shocked at first, but quickly recovered from his shocked state. He embraced Izuku in a hug, letting the greenette cry into his shirt. “Don’t worry, Izuku! For I, Bakugo Katsuki, will be your hero!!” Katsuki proudly said once the two broke apart from the hug. Izuku looked confused, the hot tears still running down his flushed cheeks. Katsuki quickly whipped away the tears, gently as to not hurt the no-longer-crying child. “Huh? W-what do you mean by that?” Izuku asked, tilting his head slightly. Katsuki smiled proudly, grabbing the greenette’s hands.

“I mean, I’m gonna protect you and become your hero!!” Katsuki confidently said, holding his future wife’s hands. Izuku giggled, his mood instantly boosted with the knowledge that Katsuki would be there for him always, and would even be his hero. “Kacchan, I promise one day, even if I don’t have a quirk, I’ll be your hero!! No matter what!!” the greenette stated, smiling wide. The blonde smiled with him, but let go of one hand and held out his pinky finger. “You gotta promise me it. One day, we both will become each other’s heroes and get married! You will be my lovely wife someday, no matter what!” Katsuki promised, still holding out his pinky for Izuku, who intertwined his pinky into it. Their promise had been sealed, one day, they would carry out the promise they had made, but surely, they would never forget about it.
