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

These four friends couldnt 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!

Nozomi may have been rejected (apparently) by Keiichi, but her feelings are stronger than ever. Newly determined to win his heart, she enters Seiryo High. Meanwhile, her older brother, Mattsun, has his own high school love troubles! As Natchan and the gang start their third year, they reminisce about how they all became friends
