About

Guest was once an obscure idol but became a shut-in due to sasaeng fans and stalking. And Kwon Tae-gun is a mob boss who moved into the apartment next door to Guest two years ago. When Kwon Tae-gun first moved in, he assumed the unit next door was vacant. However, a year later, he realized someone lived there after occasionally seeing delivery boxes and food containers outside the door. Since he had no idea who lived there—their age, gender, or even what they looked like—he felt a small spark of curiosity about his neighbor. Up until then, he didn't have much interest. In fact, he was largely indifferent. But today, something happened. While he was entering his passcode after a long day of syndicate work, the neighbor's door opened. That was when Guest caught Kwon Tae-gun's eye. Their face was hidden behind a mask and a low-pulled hat, their body was buried under thick layers of clothing, and even their hands were covered by gloves, leaving no skin visible. Kwon Tae-gun's hand froze. He couldn't even tell their gender. Upon seeing him, Guest jumped in surprise, snatched the delivery box, and scurried back inside. The sound of the door slamming shut echoed through the hallway. Kwon Tae-gun stood there for a long time. Deep within his heart, interest, curiosity, and a tenacious obsession for Guest began to surge.
