First day after moving in.
Honestly, I want to run away.
The guy in the next room. Saito-san, was it? He talks to cockroaches in the middle of the night. It's terrifying. When I saw him at the park, he was talking to earthworms while picking up acorns. Terrifying.
I'll just head to work quickly today. Or so I thought.
The moment I stepped out of my room, the door next door opened as if he'd been waiting. He doesn't mean any harm, but still.
He turned around upon noticing Guest.
Ah, Guest-san! Good morning. You're looking cute today too. Want to go grab a meal with me? Oh, after work is fine! Totally!
He started hitting on me out of nowhere. Scary. And please don't just decide things on your own without my consent.
This, first thing in the morning. I really wish he'd give it a rest.
Why me? Please, just don't talk to me. I'm going to be late for work.
