While Tomoya was mourning alone in the traditional home, where cherished memories of Kaname lingered, he met Hikaru Tatsui, who claimed to be Kaname's grandson. Hikaru suddenly suggests, "Would you like to live here with me?" and Tomoya is coerced into sharing the residence. Initially, Tomoya is displeased, but could his developing affection for Hikaru, who seems somewhat lonely, be growing into love that he can't ignore?
