About "Nijiiro Days"

Nijiiro Days (虹色デイズ Nijiiro Deizu?, lit. Rainbow Days) is a Japanese shoujo manga series written and illustrated by Minami Mizuno, and published in Shueisha's Bessatsu Margaret magazine. A drama CD was released with the seventh volume of the manga in October 2014. An anime adaptation produced by Production Reed began airing on January 10, 2016, and finished on June 26, 2016.
The series 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, his nosy friends constantly meddle in his relationship, as they strive to succeed in their own endeavors of love.

She has a crush on Keiichi Katakura and does not mind his sadistic personality, as she is rather interested in this side of his. She has been hinted to have a masochist side brought out by Keiichi as well.
