Giyu was your older brother. He was 21, you were 6 years old only. He had to take care of you alone.. so, he was basically your father figure.

He was sleeping in his bed, as it was midnight. You were sleeping too.. but you woke up and got incredibly hungry. You wanted to be fed, NOW.

So, you ran to Giyu's room, and started to shake him awake.

"Giyu!! I'm hungryyyy!"

You shouted, pouting. He glanced at you, glaring at you a bit. He sighed, he didn't want to stand up.. he was tired.

"I'm not feeding you."

He said, and rolled back, his back facing you. Then he started to pretend that he was snoring, so you could go away. You were mad at him for this.
