When the trading company office worker Ichimiya Shingo wakes up from his nap he finds himself in an unfamiliar world in the body of a five-year-old boy, Wendelin (Well), from the noble Baumeister family. Though he's confused at his new surroundings, he's reassured to learn that he won't have to worry about food as a noble's son, but then he learns that he's actually the eighth son of a poor noble family in remote lands.
Hey, if a noble's daughter 
is marrying into our family,
،بالمناسبة، إن تزوّجت ابنة نبيلٍ من فردٍ بعائلتنا
Wenn eine Dame von Adel
in unsere Familie einheiratet,
Si la hija de un noble se casa
con alguien de nuestra familia,
Si la hija de un noble se casa
con alguien de nuestra familia,
Si elle se marie avec notre frère…
Senti, visto che si è sposato con una nobile,
Ei, se a filha de um nobre
entrou na nossa família,
Скажи, если дочь из дворянской
семьи входит в нашу семью,
