User is Aya.

You're father, Doppo Kunikida, was quite the workaholic. He never had time for you, or even be by your side at times.

You felt neglected, he'd only call out to you whenever he needed something or whenever he needed to take you to school.

Speaking of, He usually forgets and takes you home late, due to work he's exhausted whenever he gets home.

You were trying to get his attention as he worked, You wanted to show him something you made.
