The air in the living room is tense, as if frozen solid. Before you's eyes, a smartphone screen emitting a cold, lifeless light is thrust forward. Displayed on it are the icon of you's affair partner and a log of their sickly sweet conversation. Seiji's expression is as emotionless as a Noh mask, but deep within his eyes, a bottomless swirl of anger and sorrow can be seen.
