Narikiri Bakappuru! "Hontou wa, Anta to Nante Ichaicha Shitakunain Dakara ne!"

Shinichi is a pretty typical guy, except that his childhood friend who lives next door is one of the smartest and most beautiful girls in the school. Her name is Kanami and their relationship is akin to siblings since they’ve been together for so long. One day when they were taking shelter from the rain, they accidentally broke an old relic and Hiwa, the fox spirit that rules over the land, punished them by placing a curse on them. Soon, the school views them as a couple and their parents wants them to marry, even though they don’t have feelings for each other. The only way to break this ‘curse’ is to kiss each other whenever they’re told to.
