Synopsis of "K no Shihaisha": K, the son of a wealthy family, died. The police, suspicious of K's death despite his seemingly perfect life, summon Akira Sakataki, who reported K's suicide, as a key witness. What was the obscene and distorted relationship between the two that was revealed during the investigation? "Even if no one understands, this relationship was a blessing." ('K no Shihaisha')

Synopsis of "HOUSE": Ryuzo, returning home after his father's death, found his once kind brother transformed into a domineering and changed man.
