Falling Drowning volume 1

Honatsu just started her second year of high school, and already rumors are floating around that she's dating her childhood friend, Toma. While Honatsu isn't totally opposed to the idea, she's not sure what she feels for Toma can really be called love. But when aloof transfer student Shun Tachibana appears, the waters get even muddier... How does Shun connect to the past she can't remember? And can Honatsu decide what she truly wants, when her head and her heart are pulling her two different ways?
