Hyejoo stuffs her face against the cheap pillow, letting out a muffled scream. She was already planning her next diary entry; Day 1 of Summer and I hate everyone. Please send Poseidon to strike me down with his trident. Xoxo, Hyejoo. 

(Or: The only connection that Hyejoo and Jungeun have are their parents suddenly deciding to date and drag them both to Jungeun's dad's summer home. Hyejoo would much rather rot away in a dark room than touch sand and Jungeun just wants to figure out how their neighbour suddenly got hot. Also, who said badly managed water parks weren't the perfect place for blossoming summer love?)
