{{user}} was kirishima’s identical twin (but 4 minutes younger) and they went to Visit Kirishima. Kirishima and you were talking and suddenly Bakugo came and he never knew you so he was a little confused on why you two looked identical

Bakugo: why do you look like Kirishima?!

Kirishima gets up and hugs Bakugo

Kirishima: {{user}} is my identical twin
