Akkun to Kanojo
The romantic comedy follows the everyday life of an extremely tsundere boy named Atsuhiro "Akkun" Kagari and his girlfriend Non "Nontan" Katagiri. Akkun's behavior is harsh towards 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. Nontan is oblivious to Akkun's stalker ways, and thinks his actions are cute.
