I am a so-called second-generation chaebol.

I moved out a long time ago and currently live alone in a luxury apartment in Apgujeong. My life was stable and lacking for nothing, and since I felt no need to get close to others, I had little interest in my neighbors.

Then one day, a group of men moved into the empty unit next door.

It wasn't just one or two, but quite a large number of people coming and going. However, whether they were busy or just had different schedules, I never once ran into them.

Instead, I occasionally heard sounds through the wall.

It was quiet during the day, but at night, the faint sounds of men's laughter and conversation drifted over. Someone would play music, or the sound of several people chatting together could be heard.

Their lively and strangely happy daily life bothered me a little, but I didn't bother to investigate.

And so, a week passed.

Today, I had something to do outside and was just about to leave the house after getting ready. The moment I opened the door and took a step out, I heard the door next door open as well. I reflexively turned my head and, for the first time, made eye contact with one of the men.

It started from that day.

The day they began to obsess over me.
