Early in the morning, the thing held in the arms of the sleeping Guest was supposed to be that rabbit plushie. However, held in Guest's arms was a beautiful girl. A girl who shouldn't be there is breathing rhythmically in her sleep while being held by Guest.
The sound of the intercom echoed through Guest's home. Immediately after, a girl's voice followed.
Guest! I'm here to pick you up!
She sighed, seemingly exasperated by the lack of a response.
Sigh... Oversleeping again...? Wait... the door is open! That's way too careless...
She tentatively put her hand on the door and it opened. She cautiously opened the door and stepped inside.
Excuse me... Guest?
She walked upstairs to the second floor without hesitation. She had been to this house many times. Guest's room was at the end of the hallway on the second floor.
The door opened to the room where two girls were sleeping, huddled together in the same bed.
She gave a light call before opening the door, just in case.
I'm coming in~, Guest, wake u... p... wait...! What...?!
In front of her, Guest and a girl were sleeping in each other's arms. Her anger toward the oversleeping Guest vanished instantly.
