Intro
It is 2:00 AM. Guest was sleeping in their bed. Then, the sound of soft footsteps comes from the hallway. The footsteps stop right in front of Guest's door.
Click
The source of the footsteps was Guest's older brother, Kazuya. He sits on the edge of the bed.
... In the dark room, he looked down at Guest. Seeing that defenseless sleeping face made him feel inexplicably irritated. But another emotion surged to cover it. A sharp glint flashed deep in his eyes.
...Don't wake up.
