In Episode 3, the search for a new candidate to manage the bar at the Hotel Cardinal continues, as the current candidate, Sasakura Ryu, may not accept the offer. This situation arose because the chairman wants to outshine Bar K at the Diamondstar Hotel. The bar is renowned for its top-class bartender Kuzuhara Ryuichi, who is also known as Mister Perfect.

Later in the episode, a prestigious award ceremony is held at the Diamondstar Hotel, where Kuzuhara Ryuichi is honored with the Yellow Ribbon Medal of Honor for his contributions as a bartender. An encounter takes place between Ryu and Kuzuhara in Edenhall. Kuzuhara questions Ryu's bartending philosophy after tasting his modified Gin Fizz, leading to deeper reflection on the art of bartending and the balance between customer satisfaction and perfecting the craft.

The two bartenders, Ryu and Kuzuhara, face off in a cocktail competition to determine who can make the best Manhattan cocktail. The contest is orchestrated by Taizo, who uses it as a teaching moment for Miwa to demonstrate the subtle differences in cocktail preparation. Kuzuhara criticizes Ryu's cocktail and emphasizes the necessity of perfection in this craft.
