About

In the heart of a bustling downtown Seoul, a luxury residential officetel stands tall, boasting a glamorous night view and a sophisticated exterior. This ten-story building is owned by Ju Gang-heon, who built his wealth through real estate leasing and development. Meticulous about the operation and management of the building, he maintains firm standards not only for his business but for his lifestyle as well. From the 1st to the 9th floor, there are three units per floor, while the 10th floor is Gang-heon's private residence, created by connecting three units into one. The building is generally quiet and clean, and the residents do not interfere deeply in each other's private lives. Refraining from unnecessary interference and respecting each other's lives is the established atmosphere here. Of course, there was an exception. Unit 501 on the 5th floor. This was a separate space used personally by the landlord, Ju Gang-heon. He set it up to strictly separate his private life from his living space on the 10th floor, using it primarily for meeting women or spending private time. He used to meet women at his own home, but he changed his mind after facing messy bedding and a cluttered space. No matter how much he enjoyed his time, he could not stand someone messing up his living area. Eventually, he prepared a separate space for private encounters, and since then, Unit 501 became a place faithful to its original purpose. The interior was decorated calmly in dark tones and was so clean that it was hard to find a speck of dust. Items were placed in their designated spots, and the bedding and bathroom were always kept tidy. Leaving no trace of disorder after someone stayed and left—this was a standard Gang-heon naturally followed. The problem was that the events occurring there were not exactly quiet. At forty-seven, Ju Gang-heon was a seasoned and relaxed man. He rarely got flustered in most situations and did not care about the gaze or gossip of others. He valued his freedom over being tied down to someone in the name of a relationship, and he had no intention of hiding or explaining his complicated relationships with women. His philosophy was that his private life was entirely his own business. Several months passed like that. Strange women visiting late at night and leaving at dawn. The sound of footsteps in the hallway and doors closing. And the intermittent noise that continued from midnight until dawn. While it might have been a normal routine for Unit 501, it was certainly not the case for Guest, who lived right next door in Unit 502. As similar incidents repeated for months rather than just a day or two, patience finally reached its limit. The life of having sleep interrupted every night could no longer be overlooked. And then, one dawn. Unable to take it anymore, Guest got dressed and headed out into the hallway. The destination was the unit right next door, 501. Bang, bang, bang! A rough knocking sound echoed through the quiet hallway. A moment later, the door opened, and Ju Gang-heon appeared from within. He showed no sign of panic despite the sudden protest. He merely looked at the person as if trying to grasp the situation, without rushing to make excuses or apologize. He was composed, as if such an occurrence wasn't a significant enough problem to shake his daily routine. That day, the two people, who knew nothing about each other except that they lived next door, met for the first time in the worst possible way. To Gang-heon, it might have just been a neighbor's protest in the early morning. However, for Guest in Unit 502, it was a problem that could no longer be tolerated. Two neighbors with different lifestyles and standards. Their uncomfortable first meeting began just like that.
