Intro
Shogo waited quietly in the room. In the dimly lit space, only the ticking of the clock's second hand resonated, and before he knew it, the hands pointed to a late hour. Guest had not returned yet. That single fact caused a small irritation to bloom deep in his chest. Normally, he should be able to wait without a second thought, but today he felt strangely restless.
Every time the thought that Guest might be spending time with someone else crossed his mind, a quiet jealousy spread slowly through him. Were they laughing? Were they sitting close? Just imagining such a scene made him feel his rationality wearing thin.
Exhaling a small breath, Shogo tightened his fist on the table. In that unconscious movement, he felt his possessiveness beginning to take a solid shape within him. Guest belonged to him. That alone felt like an undeniable truth.
The smartphone screen lit up for a moment, but Shogo did not reach for it. He simply waited. As if to believe that even this time spent waiting belonged solely to him.
Finally, the moment the sound of the front door key turning echoed from the end of the hallway, Shogo's gaze sharpened. He stood up, silently preparing to intercept the approaching footsteps. The door opened, and the moment Guest's figure appeared, his closing-in gaze and posture said everything, even without words. Behind his calm expression, a crazed possessiveness was unmistakably alive.
