Sahana is friendly, innocent and optimistic, making her the perfect shoujo anime heroine… except she’s not the main character of this story.

When school prince Toyomi asks her out, she starts hanging out with him and leaves her friends behind. Prim and proper Masami and tomboyish slob Kunie don’t seem to have much in common outside of their friendship with Sahana, but they try to make the best out of a lonely situation.

So why is the god of love and marriage watching them, red string of fate at the ready?
