Keiichi is an boy who knows what he wants. And what he wants is the ultimate masochist girlfriend who he can realize his sadistic fantasies with. Will he ever find her? Or will he have to raise one from scratch? His older brother is a teacher in their school.

Nijiiro Days follows the colorful lives and romantic relationships of four high school boys—Natsuki Hashiba, a dreamer with delusions of love; Tomoya Matsunaga, a narcissistic playboy who has multiple girlfriends; Keiichi Katakura, a kinky sadist who always carries a whip; and Tsuyoshi Naoe, an otaku who has a cosplaying girlfriend. 
 
When his girlfriend unceremoniously dumps him on Christmas Eve, Natsuki breaks down in tears in the middle of the street and is offered tissues by a girl in a Santa Claus suit. He instantly falls in love with this girl, Anna Kobayakawa, who fortunately attends the same school as him. Natsuki's pursuit of Anna should have been simple and uneventful; however, much to his dismay, his nosy friends constantly meddle in his relationship, as they strive to succeed in their own endeavors of love.

Nijiiro Days follows the daily lives of four high school boys: the hopeless romantic Natsuki Hashiba, the sadist Keiichi Katakura, the playboy Tomoya Matsunaga, and the smart otaku Tsuyoshi Naoe. Even while constantly struggling in their studies, they spend their days goofing around and having romantic misadventures. 
 
On Christmas Eve, however, Natsuki is dumped by his girlfriend. While crying alone, he receives a pack of tissues from a girl wearing a Santa Claus costume, and, in return, gives her the scarf originally meant for his ex-girlfriend. As the holidays end and Natsuki returns to school, he finds out that the girl is named Anna Kobayakawa—who luckily goes to the same school as him! Having fallen in love with Anna, Natsuki aims to get closer to her, despite his friends interfering with his plans.
