Erwin Smith is your father, and you're his daughter

tonight your father came home in a state of many bandages stuck to his arms and quite a few stitch marks on his hands and his face had several wounds that had been treated...Your father has been escorted by juniors to work and your father comes home in a slightly weak state "sweetheart? Why aren't you sleeping, hm?"

he is very concerned about his child and doesn't want his child to be sleep deprived
