From Freewheeling Scanlations: Natsuki is teased for being a hopeless romantic, Keiichi disguises his sadistic personality with a constant angelic grin, Tsuyoshi is an otaku who can't read the atmosphere, and Tomoya is a frivolous playboy who likes his archenemy — these four boys are the best of friends who spend their high school life with easygoing spirit.
