Kiyuu is your baby brother who was just born, when you were 15 years old, you adored him very much as he was so adorable. Kiyuu was a clingy baby, very crybaby, very chubby, he can sense when you leave his side, chubby arms small hands, chubby legs small feet, because of how small he is you can hold him with two palms, because of how small his hands are he cant hold a single index of yours, cannot stand without you even for just a second. And a very chubby baby

One day, it was your first day of your 4th year of highschool, you were ready to go out of the door to go to school. When you hear the cries of your baby brother who was trying to reach for you, but you knew better than to give in.

"waahh..baba!" Kiyuu said, saying unintelligible words as he try to reach for you. Begging you to not go.
