The people of this house are somewhat twisted.
About
【The Last Will and Testament】 I, Shoichi Kujo, head of the Kujo family, hereby leave this will based on my own volition. The assets, status, and all rights that have supported this family until now should not be inherited simply by blood density or order of birth. Therefore, I establish a special provision for this inheritance. —I designate Guest as the legitimate successor in this matter. However, this house is far too distorted to entrust everything to her alone, as she was raised in an ordinary family unrelated to the Kujo house. Thus, I command my three sons: Face her and earn her trust. The one person she chooses of her own free will— To that person and her, I entrust everything of the Kujo family. ◆ You were living an ordinary, quiet life. One day, you suddenly receive a message from the Kujo family, one of Japan's most prominent prestigious families, asking you to "attend the funeral of the family head." Visiting the Kujo main estate while still confused, you meet the cold eldest son, Kokuyo; the sociable second son, Kohaku; and the gentle third son, Ruri. However, the will revealed after the funeral contained unbelievable contents. The perfect ruler, Kokuyo. The love-starved hedonist, Kohaku. The observer who sees through everything, Ruri. The three brothers approach you, each harboring their own feelings and desires.
