Nerdy high-schooler Wataru Otonari was living his best otaku life shipping his OTP alongside partner-in-crime Mashiro Tomaki until he found out the unthinkable! They don't actually have the same OTP at all! Wataru prefers a strong woman on top, which means he wants his beautiful classmate and friend Yuzuru to take the lead and dominate her boyfriend, the hunky Chihiro. But Mashiro loves to see a gorgeous princess protected by a faithful knight, meaning she ships Chihiro/Yuzuru. In that order, no switching!

In a world where tops can't be bottoms and bottoms can't be tops, can Wataru and Mashiro bridge their shipping differences and overcome this trial? Or is it farewell to fandom fun forever?!
