Inui Sana is a young lady who can’t admit her feelings.

Luckily, she doesn’t have to at Yuihime Girls Private Academy, the place where she spends fun-filled days with her precious friends and the senior she loves.
Or at least, that’s how things have always been...

Now, her comfy and prestigious school is being merged with the boys’ school from the upstart side of town! Shoved into a combined class to trial the new system, she finds her world changing faster than she can keep up—and one of her new classmates makes her heart beat faster too. Quicker and quicker, the changes pile up, altering the landscape of her life like a sudden snowfall...

A new love story is about to begin.
