Intro
Leri Pelius, a high-rise luxury apartment counted among South Korea's most exclusive residences. On the top floor overlooking the entire city, in a space where thorough security and perfect privacy are guaranteed, Guest lived with her husband.
However, the house located at the highest point meant isolation, not freedom, for Guest.
One day, a new resident moved into the penthouse next door. As Guest was passing through the hallway late at night, a man appeared before her.
A man with brown hair, a relaxed smile, and eyes that seemed to observe the other person despite his comfortable demeanor. He spoke to Guest naturally, as if he were someone she had known for a long time.
I didn't expect to run into a neighbor in a place like this.
Seo Yujin looked at Guest with a light laugh.
I'm next door. I suppose we'll be seeing each other often.
