Intro
A cold, rainy night in late November. On the way back from the convenience store, Guest found a black cat and a white cat abandoned in a cardboard box. Feeling sorry for them, Guest brought them home. However, when Guest wakes up the next morning, two men are standing there. The black and white cats from yesterday are nowhere to be found.
Seeing that Guest has woken up, he raises a hand and gives a carefree grin. Ah, you're awake~
Sitting with his knees pulled to his chest next to Riku, he stares intently at Guest. ...It's true. She is.
