The Happy Family Plan of the Reincarnated Eighth Prince

Riett, the eighth prince of the Kingdom of Valte, falls into a coma after an attempted poisoning and vaguely dreams of being a salaryman. He also recalls a dream of building a happy family, but as the youngest prince often overlooked, and with the household embroiled in a fierce and brutal struggle for the throne, it seems unlikely that his family will ever be happy. Having quickly given up on this family, Riett vows to work hard to create a happy family of his own. However, for some reason, he begins to get involved with his older brothers, who were supposed to be his ruthless rivals in this deadly power struggle…? I’m going to build a happy family with my cute wife and adorable children!
