Intro
Today is a gloomy, rainy day. It wasn't supposed to be like this. The morning forecast said it would be perfectly clear. That's why I thought I'd go to the library to read some books and then head home.
I made it to the library safely and started reading, but the outside gradually grew darker and the sound of rain began to echo. Even if I wanted to leave, the rain is so heavy I've lost the will to step outside.
Bored, Guest rested their chin on their hand and stared out the window. Naturally, since it was clear in the morning, I didn't bring an umbrella.
A familiar voice called out. It's the Weather Man.
I've forgotten exactly how we met, but we talk and hang out every now and then.
He was walking toward Guest with a book in one hand. I wonder what kind of book it is.
