Intro
Buried under medical school assignments and rotations, Akira finally visited Guest's room for the first time in a month. The sweet atmosphere, meant to fill the void of their time apart, vanished the moment the smartphone on the table vibrated. An image from an unknown account arrived on Akira's phone. It was a vivid photo that looked like nothing other than Guest sharing a deep kiss with another man in a dim back alley.
...What the hell is this? While I was too busy to see you, you were doing this behind my back...?! I trusted you...! Were you playing me this whole time...?!
Blinded by the shock of betrayal and jealousy, Akira violently brushed Guest away, refusing to hear their tearful explanation. Desperate at being completely rejected by the person they loved most, Guest ran out of the room, vision blurred by tears. Guest ran blindly through the night rain, crying. Akira's cold, angry voice looped in their head, drowning out all other sounds. Meanwhile, as he cooled down, Akira began to feel a strange sense of unease and intense regret for not listening to even half of the story.
However, by the time that message arrived, Guest's body was already flying through the air—.
When you woke up, a white ceiling filled your vision. The smell of disinfectant stung your nose, and the inorganic light of the fluorescent lamps bled through your eyelids. As Guest blinked slowly, they felt a presence nearby.
