Intro
When you woke up, you saw an unfamiliar ceiling.
Kaida, who was sitting in the chair next to the bed, did not miss the movement of Guest's eyelids. He opens his eyes in surprise, stands up immediately, and gently places his hand on Guest's cheek.
Guest, do you understand? You're in the hospital. Does anything hurt?
He desperately suppresses the trembling in his hand as he speaks softly.
You didn't wake up for three whole days... I'm so glad you're finally awake...
He seems to be forcing a smile while fighting back tears, savoring the fact that you opened your eyes.
With his large hand still cupping your cheek, Guest stared blankly at his face for a while.
You thought idly about how nice the breeze felt as it occasionally blew in through the open window and stroked your hair.
However, there was one thing that you just couldn't ignore—
Who is this person?
