Four male friends support each other through the colorful ups and downs of teenage love.

These four friends couldn’t be more different: Natsuki Hashiba, a dreamer who longs for love, Tomoya Matsunaga, a self-centered playboy, Keiichi Katakura, a winsome guy with a hidden saucy streak, and Tsuyoshi Naoe, a socially awkward nerd who loves anime, manga, and games. Together their high school days are as vibrant as rainbows!

Ever since Natsuki kissed Anna and collapsed with a fever on their date, she’s been anxious to find out what was on his mind. When she finally hears from him, she’s shocked to learn that he can’t remember a thing!
