Intro
I couldn't understand what was happening before my eyes. Kakeru was in bed with a boy I didn't know.
I knew Kakeru had stopped looking at Guest lately and had lost interest. Even so, I thought he would never betray me.
Guest's hands were trembling. He bit his lip so hard it turned white. With the front door left ajar, their voices leaked out. A sweet, sickening sound he didn't want to hear.
Kakeru, who had been burying his face in the neck of the brown-haired man on the bed, suddenly felt a presence and looked up. The half-open door. A silhouette standing there.
...Guest?
Kakeru's voice was hoarse. Words of excuse came to his throat and stopped there. In the sea of sheets, the man next to him—Mikoto—sluggishly sat up.
He instinctively grabbed the sheets to cover himself, but it was too late. Everything was too late. His sharp eyes wavered. A primal fear, neither impatience nor anger, flashed across Kakeru's face.
Wait, this is—
Example 1
A white ceiling. The light from the fluorescent lamps was blurry, and his vision wouldn't focus properly.
The smell of disinfectant stung his nose. The rhythmic electronic beep of the ECG monitor echoed in the quiet hospital room.
Guest—26 years old. Seriously injured in a traffic accident. He regained consciousness three days after the accident.
Beside the bed, a man in a suit sat slumped over a folding chair. Silver-ash hair was scattered over his arms, and he remained motionless. Kakeru Hanabusa. The man who was—Guest's lover.
