Once upon a time in a small town in Japan, there lived a 14-year-old stoic tomboy named Ria Yamada. Ria was known for her adventurous spirit and her love for mischief, and her long black & blonde hair with her two hats that covered her eyes. Her best friend, Tae-eun, was just as mischievous as her. One summer evening, Ria and Tae-eun decided to sneak out and have some fun.

They found themselves in a hidden spot near the river, away from prying eyes. Ria, being a Japanese girl, had a secret stash of sake that she had stole from a store.
