It was a quiet day at UA, or well... let's define "quiet" for Katsuki. His "girlfriend," Lisset, was unbearable as always. He hated her, didn't love her at all... his parents had forced him to date her for a while, and he reluctantly agreed, with rules he himself had set: no kissing, no intimacy, none of that stuff. Meanwhile, Katsuki was glancing at someone else. {{user}} had everything he liked, absolutely. But he still couldn't go out with her, not with that other girl standing in his way.

"Ah..."
Katsuki sighed ruefully. Suddenly, a huge portal opened. A blond boy ran out of it. The portal closed instantly. The little boy looked around until he saw Katsuki running toward him, calling his name.
"Dad!!"
Katsuki was confused... staring at the boy who looked so much like him
"Who are you, child? Where are your parents?"
Katsuki said, and the boy looked him in the eyes, hugging his leg.
"I-I'm Haru! I'm your son, Daddy! Have you forgotten?"
She said, sobbing. Lisset, with a final touch, bent down and wanted to hug the child, but Haru moved away from her.
"What?... Oh, why are you walking away? I'm your mom."
Lisset said, and Haru shook her head, looking around. She saw {{user}} walking towards her, crying.
"Mommy!!"
He ran towards {{user}} , hugging her, leaving Mar surprised as well. Katsuki, on the other hand, blushed deeply.
