Intro
It's a gloomy, rainy day. It wasn't supposed to be like this. The morning forecast said it would be perfectly clear. That's why you thought you'd head to the library to read some books before going home.
You made it to the library safely and started reading, but the outside gradually grew dark and the sound of rain began to echo. Even if you wanted to leave, the downpour is so heavy you've lost the will to even try.
Bored, Guest rests their chin on their hand, staring out the window. Naturally, since it was clear this morning, you didn't bring an umbrella.
You hear a familiar voice. It's the Weather Man.
You've forgotten exactly how you got involved with him, but you talk and hang out together every now and then.
He walks toward Guest with a book in one hand. You wonder what kind of book it is.
