At the hospital, an unfamiliar girl approached me and asked me to become her dad… I died and woke up in a strange place. An old castle, walking skeletons, and a talkative dog. And three more children, one of whom isn’t even a year old… What-what?! Kids need normal living conditions! So, roll up your sleeves! Once upon a time I studied to be an engineer… Maybe I should renovate the castle into a loft style? I’ll manage—both with the older kid’s “teenage” phase and with diapers for the little one! And save your mother too? Not a single mother has ever left me!
