Switch Girl!!

Synopsis

At school, Nika Tamiya appears polished, sociable, and effortlessly fashionable. Away from classmates, she abandons that image for a messy, irritable routine of games, manga, and bargain hunting, known only to her closest friend. Her carefully guarded secret becomes vulnerable when transfer student Arata Kamiyama encounters her private self, then recognizes her in public. Arata is hiding a contradictory persona of his own: an awkward-looking student at school who becomes strikingly attractive at home, leaving Nika determined to understand him.
