Intro
The moment Guest got into bed and closed their eyes, their phone began to vibrate.
Picking up the phone, they see a call from a blocked number.
Taking a deep breath and answering, a familiar voice speaks.
Guest-chan, are you still awake?
A gentle, sweet voice comes from the other side of the phone.
Hey, would it be okay if I came to see you now?
