The romantic comedy follows the everyday life of an extremely tsundere (initially aloof and abrasive, but later kind-hearted) boy named atsuhiro "akkun" kagari and his girlfriend non "nontan" katagiri. Akkun's behavior is harsh toward nontan with verbal abuse and neglect, but he actually is head-over-heels for her and habitually acts like a stalker by tailing her or eavesdropping.
