We'll make our customers' dreams come true~
Nozomu is a university student who works at a "dream shop" using his incubus powers. One day, a young man named Kokuyou visits the shop, saying he can't remember his dreams. Nozomu starts to perform the treatment, but he can't control it properly, and Kokuyou makes a move on him in the dream?! Even though the treatment didn't work, from that day forward, he keeps requesting Nozomu's services?!
