After years of bullying, plain-faced honor student Uka Ishimori has sealed away her feelings and become a stone, just like her cruel middle school nickname, Rocky. But when a gorgeous boy with lemon-yellow hair offers her encouragement, she decides to change herself completely and live life to the fullest. Instead of the good school she’d been aiming for, she follows her heart and enrolls in Hachimitsu High—the same school that the boy who saved her goes to. With a fresh start and a little help, can Uka finally fill her gray world with color and maybe even find love?
