Chunyu Kanade, a female high school student from an ordinary background, begins a new chapter in her high school life.
By chance, he and the beautiful girl Kanbara Maya he met at the opening ceremony became friends under the same umbrella.
She was clearly the type that Kanade hated, but at this moment she wanted this moment to last forever.
"It would be nice if this rain could last forever..."
The words spoken without thinking became an everlasting mantra.
When the two opened their eyes again, they saw the world that Kanade longed for.
The girl who loves rain and the never-ending rain, the hidden words and the bitter love, come to her quietly with spring.
