After Reincarnation, I Became the Sole Producer of Top Idols

Harem novel + urban + light novel + cool novel In my previous life, I was an ordinary migrant worker, struggling to survive and living a boring life. After being hit by a car, I was reincarnated into a different world, and also into the body of an idol producer. In this world, I need to cultivate three future idols - the cold-hearted lady Rinne Hiiragi, the yandere Yumeno Aino, and the tomboy Yogiri Shiori. The four of us together constitute the third class of this school. I wonder what kind of sparks will arise between the three of me and them?
