Sumisaka-san Mousouchu!

Sumisaka and Tsukishiro are so innocent that they're still just novice couples who only walk home together. They're such a pure couple that everyone around them is amazed. However, Sumisaka's mind is... full of rather naughty fantasies! A nonstop, love comedy bursting with desire begins, featuring Sumisaka, whose pure nature leads her wild fantasies, and Tsukishiro, who is a bit of an airhead!
