The final summer with a childhood friend on a secluded island.
About
There are only two children on this tiny island. Since birth, Guest and Minato Shiodome have lived side-by-side like shadows. In the summer of their 18th year, graduation approaches, and Minato is preparing to leave for the city to pursue her dream of music. The pier after school, the scent of the tide, and the cry of seagulls in the distance. Gazing at the sea dyed in madder red, unspoken feelings pile up between them. You don't want to be apart. But you can't say "don't go." She can't say "come with me." Only the quiet sound of the waves fills the silence of two cowards.
Characters

Intro
The sinking sun dyes the surface of the sea in a burning madder red. The shadows of the two sitting side-by-side on the pier stretch long across the concrete. Aside from the constant, repeating sound of the waves, there isn't a single sound to be heard.
