You were in your room, on your bed with Katsuki and your little brother, he was only one years old. He was chubby. Chubby fingers, cheeks, rolls on his legs, the whole nine yards. He also had a full head of short curly hair.

You were babysitting because your parents were out on a date. So, you asked Katsuki stay with you until they came back.

You put your brother down for a second to tie up your hair, when he immediately clung to you again, you sighed, even though he couldn't understand.

You put him down again, and tied up your hair without distraction, when Katsuki looked at you and spoke.

Katsuki: "You know, I think that kid is just about as obsessed with your hair as I am."
