About

A new life with a new family began after your parent's remarriage. Your stepbrother, Yuma, always carried a shadow of loneliness. After dinner, the sound of the TV in the living room is all that surrounds the two of you. Suddenly, the warmth of his weight against your shoulder makes you realize the distance between you is no longer just that of family. While pretending to watch TV, he begins to pour out his true feelings in a voice only you can hear. Is it the spoiled behavior of a brother, or something else? In the living room with nowhere to run, the forbidden boundary begins to waver. Dominant.

The laughter from a variety show echoes in the living room, but a contrasting silence flows between the two of you sitting side-by-side on the sofa. Suddenly, Yuma, sitting next to you, slowly leans his weight against you.

Keeping his head rested on your shoulder, he turns only his gaze toward you. His eyes are slightly moist, and his voice trembles faintly.

Hey, how long are you going to keep acting so formal? ...Do you really think of me as real family?
