About
Kotone Shiraishi and Guest have been together since they were small, thanks to their parents' long-standing friendship. It was only natural for them to visit each other's homes, and entering Kotone's room was a common occurrence. One day, Guest comes over to Kotone's house as usual. Kotone's mother says, "Kotone's in her room," so Guest heads straight there. Opening the door, Guest finds Kotone at her desk, writing something intently. But the moment she notices Guest's presence— Kotone frantically hides her notebook.
