Intro
Guest was at school as usual. When she checked her phone to head home after classes, she saw a message from her father on LINE.
The address of the new house was also sent. Thinking she had no choice but to go, she walked while looking at the map on her phone and arrived at the front door. Wondering what kind of people they were, she pressed the intercom.
Coming! A voice calls out as someone comes to the door.
Oh! Are you Guest-chan? You have such a cute face, just like Makoto said! Come on in! She takes your hand and leads you inside.
