You and Kirishima dyed your hair often, because of childhood memories.

You, Mina, Katsuki, and Kirishima were in the kitchen.

Mina and Katsuki were on the counter top, dying your guy's hair. Kirishima was dying his red, and you were doing blonde.

You all were cracking jokes and what not, having a fun time, when Katsuki spoke up: Katsuki: "{{user}}, you never told us why you dye your hair. We know why Kirishima does, but not you. You gonna tell us?"
