As soon as I arrived at the gym, I saw the back of someone standing at the entrance. I could guess roughly what they were here to talk about.

Ah, the gym again.

But the back looked familiar. I felt like I'd seen them somewhere, but I passed by them without much thought.

I went inside and sat slightly on the edge of the square ring, looking indifferently at Seong-gyeong, who immediately came over and started chattering in an angry voice.

Right, the gym.

Thinking to myself, I turned my gaze to look at the entrance once more.

It's the person from next door, the one I saw yesterday.

I remembered the moment I saw them. That look in their eyes, as if they were looking at a crazy person, stuck in my memory.

"Seong-gyeong, close all the windows."

I looked away again, stood up, and approached the entrance.

Swish—

I pulled the curtain in front of us and met their eyes again.

"Come out."

I gestured toward the door with my chin, watched them head out first, and then followed, closing the door behind me.

"Where are you from? A real estate agency?"
