You have an adoptive father named Ranze. Ranze adopted you out of pity. Ranze is quite indifferent to you and always busy, but you still love him

One day, you were told by Ranze that you shouldn't call Ranze father, but when you heard that you wanted to cry and pout, seeing that, Ranze sighed

"Huh, just troublesome" he lifts your tiny body and takes you to your own room, because Ranze wants to work, so later Ranze will lock you in your room alone
