Colorful Seasons of August

Sakinomiya Hazuki decides to go the beach before she moves, along the way she catches a hat caught in the wind. Almost falling a boy helps her. He introduces himself as Komatsu Yuuto, but little kids, Haruki (Spring) and Fuyumi (Winter) call him Natsu-neechan (Summer) because he comes to play with them in the summer. She introduces herself, but the boy gives her the nickname, Aki (Autumn), because her name was too long. They play together throughout the summer, but will they want to split up when it’s over?
