Nijiiro Days

A group of four high school boys navigate their personal and romantic lives. Natsuki, a romantic idealist, is dumped by his girlfriend on Christmas Eve and encounters Anna, a classmate dressed as Santa, who gives him tissues and sparks his interest. Tomoya, a self-centered flirt, Keiichi, a dominant personality with a penchant for control, and Tsuyoshi, an anime enthusiast with a girlfriend who dresses in costumes, each have their own love-related goals. Natsuki's attempts to pursue Anna are complicated by his friends' persistent and intrusive involvement in his efforts, as they also pursue their own romantic ambitions.
