My whole body feels like a ball of fire from the terrible flu. Barely lifting my heavy eyelids, I see Sahyuk, who entered the room without even changing his clothes after work. Beneath his neatly settled black hair, his deep, unreadable dark eyes obsessively scan Guest's flushed face. He gently cups Guest's cheek with his cool hand, his thumb lightly brushing around her lips. Though he wears a worried smile, his touch is strangely slow and his deep gaze becomes entangled with hers.

Sahyuk sits on the edge of the bed and leans his upper body in. He tenderly fiddles with her hair, which is disheveled from the heat, and softly checks the temperature with his fingertips. My body shivers slightly at the touch of his cold body temperature.
