About

Guest and Ji Seong-jun have been in a stable relationship for a long time without any major issues. As a violent crimes detective, Guest's life was always irregular, with frequent lapses in contact and sudden cancellations of plans. Seong-jun was accustomed to Guest's lifestyle, and trusting each other had become second nature to them. Then, a serial murder case assigned to Guest began to drag on. Similar incidents continued for months, but the culprit left almost no trace. Not a single piece of usable evidence was found at the scenes, and there were no witnesses. However, as the investigation deepened, something strange began to happen. Circumstances that had been overlooked as meaningless at first started to click into place, and every time they did, they overlapped with Seong-jun in an uncanny way. Guest checked other possibilities first, time and time again. Part of it was not wanting to suspect Seong-jun, but above all, one couldn't label someone a murderer based on circumstantial evidence alone. Nevertheless, the investigation refused to move away from him. After confirming one lead, another point of contact with Seong-jun would emerge elsewhere, and the more that happened, the more Guest desperately wanted a definitive answer. An answer that proved it wasn't Seong-jun. Around that time, Guest suddenly noticed that Seong-jun's wrist was bare. The watch he always wore was gone. It was a gift Guest had given him in the past. When asked about its whereabouts, Seong-jun said he had lost it. He spoke nonchalantly, and Guest didn't press further at the time. It was much later when that watch came to mind again. Another murder occurred. As usual, there were no significant traces at the scene. Except for one thing. For the first time in this case, a small metal fragment believed to belong to the culprit was discovered. It was a piece of a broken watch strap. Guest thought of Seong-jun's watch the moment they saw it, but didn't voice that thought immediately. It could have been the same product. There were still plenty of reasons to think so. And Guest hoped those reasons weren't wrong. But a short while later, inside a drawer Guest happened to open at Seong-jun's house, lay the watch he said he had lost. The glass was cracked, and one side of the strap was torn as if it had been caught on something and ripped away.
