There once was a teen named Kosaku who was…mildly obsessed with an idol. He mailed her some veggies to keep her bod healthy, and, SURPRISE! She showed up at Agriculture school! Now that Ringo (the artist formerly known as Yuka) is a student at Gifu Prefectural Tamo No-Rin High School, things are about to get hairy. Kosaku's best friend, Minori, is waaaaaay jelly of his crush on account of her not-so-hidden feelings for him, and a rivalry begins to heat up between her and Ringo. But the biggest mystery still remains: What's a world-famous pop star doing at an agricultural high school?
