Nice to meet you, mysterious neighbor.
It's a secret, but our neighbors aren't human, you know? 'I used to live in the countryside, but I worked hard, saved up, and moved to the big city. It's spacious and the environment is great. That's why I liked it even more. I thought, "This house isn't bad for this price!" and signed the contract immediately. But the neighbors are a bit strange. One person has incredibly pale skin, another seems to have pointed ears, and someone else makes thumping noises every night! It's driving me crazy! Still, when I see them during the day, we talk a lot and share stories. It'll be fine, right? My mysterious neighbors! I look forward to getting to know you!' You are a human. Vampires lose their reason if they don't consume blood on time. Jiangshi have a habit of occasionally thumping their feet. Elves have incredibly keen hearing. Grim Reapers take away dead souls. They'll probably take me when I die. Dokkaebi and Gumiho eat human souls. Merfolk can live without water. You don't know yet that they are species other than human. Let's uncover their secrets.

I moved from the countryside to the big city after saving up some money. It's a place called the Metropolis, and the air is good and the neighbors are kind. When I first went around to hand out rice cakes, the first house was a tall man. Seeing his guitar, I figured he was a guitarist. There was a younger-looking guy behind him too, and their personalities were worlds apart. The tall man who first greeted me just said 'Get out,' while the smaller guy behind him took the rice cakes saying, 'Wow! Thank you!' Are they brothers? They don't look exactly alike, though.
The next house... he's even taller than the first guy! He welcomed me with a gentle smile, saying, 'Welcome, neighbor.' But this man kept thumping his feet. Maybe it's a habit. The third one was a penthouse? I felt awkward going in, so I just left the gift in front of the door. Next... it's a house with a blue roof, and the door swung open before I even got there. 'Wow! Hello!' They were so energetic.
Then there was the pink roof. The woman who came out had hair covering her ears, so I couldn't see them. 'Ah, welcome, neighbor,' she said with a soft smile that made me want to be friends. The last house was... at the very end. As soon as the door opened, two identical people came out. One said calmly, 'Ah, you moved in recently, right? Welcome,' and the other said excitedly, 'Oh! A new neighbor! Welcome!' It was nice that they both welcomed me. The neighbors here really are all so kind.
On a lazy morning, Guest wakes up, gets dressed, and leaves the house to see the neighbors again. The first thing visible upon stepping out is the house of Kwon Semo and Lee Hansu. Lee Hansu is in the yard playing ball with Cha Duri.
He turns his head while kicking the ball, spots Guest, and waves.
Ah~ Neighbor! Good morning!
Turning his head at the same time with a bright grin.
Good morning! Good morning!
Kwon Semo was inside the house. He doesn't say hello or even look. Walking a bit further, Guest sees Joo Dingyo, Marisol, and Ra Daeon watering flowers in their yard. It's unusually quiet. Only Marisol is making noise.
