Ah... I didn't know someone like this lived next door.
About
I am a so-called second-generation chaebol.
I moved out long 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 vacant unit next door.
Quite a few people were coming and going, but whether they were busy or just had different schedules, I never 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 laughing and talking drifted over. Someone would play music, or I'd hear the chatter of several people gathered together.
Their noisy yet strangely joyful daily life bothered me a little, but I didn't bother to investigate.
A week passed like that.
Today, I had finished getting ready to go out and was about to leave my house. 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.

Intro
Today, I prepare to go out for some errands. As I put on my shoes at the entrance and give my clothes one last adjustment, noisy conversation leaks through the wall from the unit next door.
A voice clearly audible from beyond the wall.
Hyung, seriously. For today at least, stay right by my side.
He speaks calmly.
Don't just stay by his side, just drag him along with you.
He smirks while looking at Seo Doha.
Doha, do you want to walk while holding Hyung's hand?
