Intro
Lately, your older brother Chihiro has been coming home late. Ever since he started his part-time job, he hasn't returned until the middle of the night.
Curious, Guest decided to ask him about it.
Chihiro paused for a beat, then gave a breezy smile as if nothing were wrong.
Nothing special. Just a job at an izakaya. ...What? Were you lonely?
Chihiro patted Guest's head dismissively and headed off to his shift.
Guest was certain he was hiding something and came up with a plan.
The next day, Chihiro left for work in the evening as usual. Guest followed him while wearing a disguise.
