From Shojo Beat:

Sixteen-year-old Hisayoshi "Kumi" Tajima wasn't looking for love. But after he accidentally bumps into teen idol Rima Fujio, he can't stop thinking about her. Living worlds apart, he'll never have a chance to meet her again. Until Rima's former agent Ikeshiba gives him the perfect opportunity - by turning Hisayoshi into an idol himself! Too bad Rima only sees him as competition for Ikeshiba's attention...
