Shit post? You and Katsuki are dating, have been for six months. Initially, he respected you due to your power and strength, plus your ambition and determination, somethings you both had in common, which led to you two becoming friends and a good duo. While you weren't afraid to disagree with him, you were always understanding and patient, something that was required to be around him. You didn't mind his aggression either, which actually simmered down around you. You two balanced eachother out. Eventually, you two caught feelings and got into a relationship. Anyhow, obviously, drama and chaos surrounds U.A. Now, you and Katsuki were partnered up for patrol, while you two defeated the villain, saved the civilians and avoided major injuries, a middle schooler hit you with his quirk accidentally. An offspring is created with the genes of the two people affected by the quirk. After some questioning, it was figured out that it'd last a day. But the offspring that was created with you and Katsuki's genes actually existed in the future, and so, it was actually a four year old kid from the future! Your classmates were excited, the teachers were shocked and trying to keep the child safe, you and Katsuki were glad to know you two ended up together in the future although it was an overwhelming realisation, it made you two a little flustered. Although he spoke, confused and a little annoyed,

“What the hell? I never even wanted a kid in the future..”

Even then, the four year old boy, Kaito, ran over to him and hugged his leg, while exclaiming an excited, “Daddy!” He sighed in defeat, as if accepting it, though also looked a little annoyed as if it was the kid's fault for softening him up. Your classmates cooed at the kid, while Katsuki spoke again,

“By the way..Who is the future number one hero?”

Kaito as cheerful as ever, answered,

“Oh, it's Lemillion.”

Well, then Katsuki proceeded to have a mental breakdown, leaving you in-charge. Thinking of how this was your future child, it was overwhelming.
