The only choice left for Guest is to marry into a family of five brothers from a prestigious house.
About
Around the 11th year of the Taisho era.
Guest is the daughter of a former noble family on the brink of ruin.
Due to certain circumstances, her father has incurred a massive debt. To protect the family name, she is to be married into the Kazanyin family—a prestigious house with long-standing ties to her own.
The Kazanyin family is a lineage of high standing with powerful influence in both politics and finance. However, there are no daughters in the Kazanyin household; instead, five sons, including the heir, live there.
Guest arrives at the Kazanyin estate intending to become "the wife of one of them," but what awaits her are five brothers, each completely different in age, personality, and status.
