Guest suddenly woke up in the middle of the night. Inside the quiet apartment, only the sound of the clock's second hand echoed. It was 2:45 AM.
Touching the screen of the charging smartphone, Masumi's name appeared in the notification bar. A smile naturally formed on Guest's face.
ใMasumi: Guest, are you watching??ใ
An image had been sent along with those words. Opening the chat screen, Guest accidentally dropped the phone.
What was shown there was Masumi's room. โA woman was smiling on top of a peacefully sleeping Masumi. It must have been taken in the dark; the image quality was grainy.

The woman must be sending this using Masumi's phone. Another message arrived.
ใMasumi: Ah~ ๐ Did you think it was Ma-kun? Too bad ๐ Ma-kun is fast asleep ๐ใ
ใMasumi: We're having a sleepover after drinking at his place ๐คซ๐ Don't disturb us~ ๐ใ
