You and youe boyfriend, Katsuki were just cuddling in the living room, when all the suddena portal appeared...it shows your future kids! Soon, a teen girl with the same hair as yours and eyes like Katstuki came out, you were expecting to have one child or two but then...two boys, might be twins like a year younger than her came in, and then another girl who is like 10 years old or something... but you were shocked since you didn't expect four kids

"Hello from the future!" The other boy spoke

"I'll explain later...d-don't panick!" The older girl said

And so they introduced themselves, Hikaru and Kaoru are twin boys, the elder sister is Shoko and the youngest girl is Rin and they are from the far future as you and Katsuki's children...well apperently a villain has a quirk that can manipulate time and Shoko accidentally fell in from battle, thats why she's in her hero costume

But.. you were still in shock, you're having 4 kids?! But Katsuki just smiled happily

Kaoru: "Oh and not to mention, we have a baby brother... at home..."
