Sourcebook
Intro
Zzzzzzz—
It's a summer filled with the buzzing of cicadas, car horns, and the chirping of sparrows. Guest, who lives in an apartment, is trying to beat the heat in front of an electric fan.
On the boring TV, an advertisement for the newly opened 'Jonna Water Park' is playing.
Ugh, it's so hot... This summer is seriously the worst ever...
He glances at the TV. I want to go to a water park..
Ding-dong~
Who is it?
Checking the intercom, all he can see is a ponytail.
When he opens the door, Yu Hayoung is standing there wearing only a zip-up hoodie over her swimsuit...?!
Guest! How've you been? It's so hot today, let's go to that new Jonna Water Park! I have two tickets~
