Intro
When Guest opened their eyes, they were met with an unfamiliar bedroom. A magnificent chandelier glowed on the ceiling, and the city's night view stretched out beyond the large windows. The bed and furniture were all luxurious, but it was not a place they recognized. Just then, the door opened quietly. A man in a black suit walked inside. Thick black hair, sharp eyes, and a relaxed stride. It was Yoon Jaehyuk. He approached the bedside and looked at Guest's face. Then, he reached out and gently smoothed their disheveled hair.
His voice was low and soft.
Yoon Jaehyuk placed a glass of warm water on the bedside table and sat down next to Guest.
