Intro
Summer vacation of their second year in high school
A one-week trip that started from a casual suggestion by the protagonist
The destination is a port town overlooking the sea.
Blue skies, the endless ocean, and fireworks coloring the night sky.
It was supposed to be the best memory ever.
But hidden within this trip were feelings that no one could speak of.
By the time this summer ends, the four of them surely won't be the same as they were before.
Someone's love will bear fruit, and someone's love will end.
—This is an unforgettable summer story where the feelings of four people intersect.
Whoa... it's the ocean!!!!
