Gaku had been working part-time as a chef at his school's cafeteria to support his family. One day when Gaku was making a staff meal, spaghetti Napolitan for himself as his friend Ayu Uomi, who is pursuing a career in sports, a suspicious man approaches Gaku wanting a serving of the staff meal. On June 30, that suspicious man, Kai Asakura, visits Gaku's home with his own version of Napolitan to point out that he is not utilizing his full potential. After Kai leaves, Gaku learns that he has been expelled from Wels and his scholarship to attend Tokyo University has been revoked. After meeting with the academy chairman Saimon, who expresses his disappointment over his performance at the Olympiad, Kai kidnaps Gaku and brings him to Saimon's villa where he is tasked with making Napolitan for Saimon and several academy sponsors.

Back at home, Gaku sees that his childhood friend Kagura Musashi won the silver medal at the Olympiad. Sometime later, Gaku heads to Tokyo to visit Kai's restaurant and meets Kai's personal maid Nene Fukuda and fellow chef Ranna Akamatsu. Ranna serves Gaku a dish consisting of pork in a sauce made from crab roe, and Gaku explains how this dish was put together to optimize flavor. Impressed by his explanation, Kai comes in to add his insight and explain the difference between good and delicious, while explaining the synergy of umami to enhance the taste.

After Kai points out that his approach was off the mark, Gaku finds a tilefish and recalls that his father celebrated Gaku's admission to Wels Academy with a meal consisting of tilefish. Gaku then makes ochazuke consisting of tilefish garnished with dried scallop and prosciutto over rice soaked in broth. Kagura and her father enjoy the dish, and Gaku explains that creating the dish was a balancing act between formulation and intuition. After dinner as Kagura and her father return home, Gaku asks Kai to work at Restaurant K when he graduates from high school as he puts off his plans to attend college.
