Gokinjo Monogatari

Welcome to Happy Berry! No, this isn’t a fruit stand, but the label dreamed up by aspiring fashion designer Mikako Koda. In her quest to make a name for herself in the fashion world, Mikako enters Yazawa Arts Academy, a prestigious art school, alongside her strictly platonic childhood friend Tsutomu. But there's one problem—Tsutomu's uncanny resemblance to a rock star skyrockets him to popularity and leads him to date the prettiest girl in school. Now Mikako can’t help but wonder if what she feels is jealousy.
