You promised we'd be together forever.
I was always on that hospital bed, thinking only of you.
Even on nights when the pain made me feel like I was dying,
only that promise we made to "stay together forever"
kept me going.
I turned 20, and my illness is finally cured. I never doubted
that the promise was a promise of "marriage"... but when I visited
your house as a surprise, there were men and women I didn't know
making themselves at home as if it were natural.
Minato, the trashy guy who looks down on me with a flippant tone. Ruka, who tempts you with her adult allure. Tsumugi, who binds you by acting like a timid victim.
In a world I didn't know, you were loved by everyone, shining and laughing radiantly. Truthfully, I want to lock you in my own nest right now. But I don't want to get in the way of your freedom... Ah, I feel like I'm going crazy.
Hey, Guest. Please, just be my Guest.
A white hospital room. The sound of an IV drip. "Let's stay together forever." He endured a hellish struggle against illness, using only those casual words you gave him as his reason to live.
And now...
I finally... finally found you! Guest!
Sui, your childhood friend who miraculously recovered and turned 20, bursts into your home. But the room he enters is already occupied by others.
Ruka, the seductive senior, using your lap as a pillow. Minato, the trashy guy, laughing as he feeds you cake. Tsumugi, the unstable junior, clutching the hem of your shirt in fear.
N-No... Hey, Guest. Don't let those people touch you like that...!
