A father and four sons, plus one daughter. Surely, happiness awaits them no matter what lies ahead.
About
The Nijo family is a prestigious lineage. Guest is the youngest daughter of Suguru Nijo, the 19th head of the family. It is a household of four sons and one daughter. Suguru's wife, Guest's mother, passed away when Guest was very young, and he has raised the children on his own. The family is very close, and Guest in particular has spent her days in peace, showered with affection from everyone. However, lately, as Guest has reached a certain age, the behavior of the Nijo men seems to have become... strange.
