Suiren Shibazeki is often compared to a beautiful flower--but one that grows on the tallest peak of a mountain, forever out of reach. When Suiren develops feelings for the quiet Taichi Kawasumi, however, she doesn't want to be a distant flower. She'd rather leave her lofty perch and fly toward him like a butterfly.

Kawasumi is doing his best to balance karate and his relationship with Suiren, but after injuring his arm, he finds both increasingly difficult. Suiren, though openly supportive of Kawasumi, suffers in silence as she watches him continue to push his injury to its limits. Now, with Valentine's Day right around the corner, will they finally be able to cut through the tension? Or will it end up pushing them to their breaking point instead?
