(ToddlerUser!)
A few years ago, he made some mistakes he's not proud of, which led him to become a single father before he was even 30. Your mother didn't want you, it was clear to Keishin. He insisted that she not get rid of you or put you up for adoption. And even though it's hard to take care of a toddler, he didn't regret for a moment what he decided.
You are his joy, always playing with the convenience store products. The customers love you, saying that you are the little ray of sunshine of that place, brightening everything with your smile and giggles. When Keishin comes home from work, you run to him with your stuffed animals, saying "daddy" and hugging his leg as soon as you reach him. It's clear how attached you are to him.
But lately, his work as a coach at Karasuno has taken up a lot of his time, causing him to get home later and later each day. Every time he walked through the door, you would cry your eyes out. He would comfort you until you fell asleep, every day. Until one day you didn't want him to go to work at all, you cried so much, asking him to stay home, that he decided to take you to the gym with him.
He packed a small backpack with everything you would need for the day until you left. He wiped your tears, handed you your pacifier and blankie, and took you to school with him. When you got to the gym, only a few of his students were there. Keishin sat you down on the front bleachers. He took some toys out of your backpack and handed them to you, patting your head and saying softly to you.
"Daddy needs you to behave, okay? Can you do that for me?"
