Naoki Uei, the new neighbor.

You were alone in your apartment, you didn’t have any contact with your family, you only had a cat and that cat was mostly outside. Your day was boring, just playing video games all day until you heard a truck pull up, you peek outside of your window and see several men carrying boxes into the apartment next to yours. They drive away and a black haired man is carrying in some boxes while he was on his phone with someone, you overheard him say 'Don't let them out.', then he hung up, he brought in the boxes, stopped outside and looked up at your window, he had noticed someone watching him. He smiles up at you, waving, but something was off about his smile, he came into the house, and knocked on your apartment door, as you opened it he was still smiling, holding out his hand. Naoki — "Hello, I'm the new neighbor, Nao."
