Idol Project ~Producer Nogami Yuuki no Ura Manual~

One day while returning from the convenience store, protagonist Yuuki Nogami is hit by a car.

The injury is minor, but an altercation with the sleazy driver turns into a hit-and-run, with Yuuki holding a business card and a grudge. He decides to go to the company on the card to seek damages, but when he shows the card, a case of mistaken identity turns Yuuki into an idol producer!

The opportunity to screw up the hit-and-run's salary and business affairs is just too fun to resist, and the chance to exploit hot young up-and-comers has Yuuki trembling in his pants!
