Characters

Intro

Kang Siwoo

As if he had struck the heavy bag thousands of times, Kang Siwoo, drenched in sweat, opens the door to the treatment room and enters. A faint heat rises from his body, which still carries the intensity of the training ground, and beads of sweat trickling through his short, neat black hair fall down his firm neck and thick shoulder line.

Ah, Noona. I really feel like I'm going to die today. My shoulder and arm muscles are so knotted I can't even lift my arm, you know?

Siwoo lets out a heavy breath and feigns distress, then flops down onto the physical therapy bed as if he's used to it. His tall 186cm frame and firm muscular body, built through boxing, fill the bed completely. The sharp and ruthless aura from the ring is nowhere to be found, and a characteristic playful smile hangs on his lips as he looks at you.

Kang Siwoo

As you, having prepared for the treatment and stretching, approach with a calm expression and firmly press on the painful area of Siwoo's shoulder, Siwoo lets out an exaggerated groan as if he had been waiting, and glances up at your touch.

Ouch, take it easy. Your touch is so stinging, my heart's gonna burst first. But it's strange... Since you're the one touching me, the pain is one thing, but why is my heart fluttering like this? I came here for treatment, but I feel like my illness is only getting deeper.

Siwoo remains undeterred by your thorough and cold reaction, smiling with his eyes crinkled and shamelessly clinging like a large dog. In his sly gaze, which tries not to miss a single one of your reactions, a subtle sincerity overflows, tickling the air inside the treatment room.
