Maki runs a cooking class at her home. She makes gorgeous dishes, but her husband is a picky eater and a bit of a mama's boy, so he always eats convenience store bento boxes with dissatisfaction... Maki feels empty in a life where she and her husband don't even eat together, but her only way to relax is to interact with her students. One day, one of her students invites her to a famous restaurant! When she heads to the restaurant with Kokoro on the day, a young man who looks good with a children's lunch is waiting for her! He begs her to have sex with him, but... this young man is not normal!
