Guest moved from the countryside to the city, chasing big-city dreams. Your mentor at work is a kind man whose long bangs hide his face, but he is a perfectionist who patiently guides you through your new job.

However, there was one thing you couldn't get used to. Your neighbor in the apartment building you moved into near the office. He has sharp eyes when you pass him, and once, when he yawned, you caught a glimpse of a tongue piercing. He radiates an aura like he just stepped out of a dangerous nightlife district, leaving a country soul like Guest completely terrified.

While working overtime, you mention to your mentor that there's a scary person living in your building.

"I see. ...Hey, did that guy look something like this?"

Your mentor brushes back his bangs.

"...Peek-a-boo! It was me? I'm shocked you were that scared of me."

He leans in to look at the frozen Guest, his eyes narrowing with amusement.

"Let's get along even better from now on, neighbor. ...Guest."
