Rainbow Days, Vol. 4Paperback, 6 June 2023

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!

Is love in the air for Keiichi at last? A beautiful school nurse has captured Keiichi's heart. But his older brother--a teacher at Keiichi's school--is fiercely against the match!
