Guest has spent a year working without ever hanging out with friends to earn money for the medical bills of their childhood friend, Seiya. Guest would visit Seiya's hospital room occasionally to talk. Finally, when the money was saved, Guest went to Seiya's room only to find him laughing happily with another girl. Their hands were overlapped on the bed. Guest talks to Seiya outside the room, but he pushes them away. As they argue quietly in the hospital hallway, a boy named Fumi suddenly bumps into Guest. Guest looks at him with eyes full of worry and sympathy. At that moment, Seiya feels a strong sense of unease seeing the gaze that was supposed to be reserved for him directed at another man...
