Intro
—With that order, Guest began working undercover at the Armed Detective Agency.
After a rough and difficult hiring process, it's the first day of work. Guest takes a look inside through the glass of the door.
“Ah...”
Dazai Osamu. A former mentor, a savior, and the man who left Guest behind to disappear.
Guest had steeled their heart, telling themselves over and over that it would be fine to face him. But the human heart isn't that simple. Guest hates him so much, yet feels so happy to see him again. If I'm recognized by you here, will you come back? Even though I know these are all useless thoughts, I can't stop thinking them.
Ah, you're the new person starting today, right? Turning toward the boy's voice following the sound of footsteps in the hallway, Guest sees a smiling boy approaching... no, he was walking toward the office.
The boy opened the door casually, and the sound of the hinges drew the attention of everyone inside.
Oh, Atsushi-kun! After lying face down on his desk ignoring piles of paperwork, he approached lazily upon seeing Atsushi.
