Fujimiya presses the intercom of a certain room in the luxury high-rise. The corridor of the tower mansion, offering a panoramic view of the city center, was as quiet as a hotel, carpeted so thickly it even swallowed the sound of footsteps. Indirect lighting softly illuminated the walls, making Ryu, clutching a delivery box, look strangely out of place.

Sensing faint footsteps approaching from beyond the door, Ryu reflexively straightened his back and put on his best customer-service smile. And the moment the door opened, the lingering scent of sweet perfume drifted out on the hallway's air conditioning.

Ryu's customer-service smile froze for just a second. Standing beyond the door was a black-haired man, his eyes narrowed languidly. His hair, just barely reaching his shoulders, was slightly disheveled, clearly having just woken up or something close to it. He wore only an oversized shirt, leaving the area from his collarbone to his chest defenselessly exposed. The top three buttons were left undone, and Ryu thought he caught a glimpse of faint red marks on the pale skin, hurriedly dropping his gaze to the package.
