Kamishima starts a discussion about welcome drinks and notes that he is satisfied with a beer from the fridge. Yukari and Miwa compare this to the luxurious offerings in 5-star hotels, which include champagne and fruit. Nishizawa emphasizes the importance of the hotel bar and the welcome drink for a traveler's first impression of a country and suggests that the drink should be memorable.

Miwa asks Judy and Leslie to share their thoughts. Judy proposes a drink that embodies the essence of Japan, while Leslie recalls a surprising welcome with zunda rice cakes and a shake at a Japanese inn. Nishizawa explains that welcome drinks traditionally consisted of sweet treats for weary travelers.

Yukari turns to Sasakura and asks for his help in developing a menu for welcome drinks. Sasakura reluctantly agrees, noting that despite his initial hesitation, he always ends up helping.

Kelvin Chen from Bar K arrives looking for a job. Miwa identifies him, and Chen explains that he was forced to leave Bar K and asks to work at Sasakura's bar to prove his skills as a bartender to his father. Sasakura agrees to let him work there.

Chen shares his background: His older brother was supposed to inherit the family's hotel business, but after his brother's accidental death, Chen was sent to Bar K to learn service. He develops a passion for bartending but faces resistance from his father, who wants to send him back to the family business. Chen asks Sasakura to teach him how to make the "Glass of God" to gain his father's approval, but Sasakura explains that such mastery cannot be taught directly. Nevertheless, he offers Chen a place in his bar.

Chen's father arrives but dismisses Chen's attempt to impress him with a Singapore Sling. His father remains disappointed and arranges Chen's return flight. Chen is determined to seek another chance to prove himself.

Miwa and Yukari notice that Sasakura is struggling with the recipe for his welcome drink. Sasakura admits that it is difficult to create a drink for unknown guests. Later, he mixes Miwa a Gin Tonic to demonstrate his bartending philosophy: to soothe the soul of the guest before him.

Chen prepares for his father's second visit. He serves a drink inspired by cherry blossoms, symbolizing the family trip they missed due to his brother's death. The drink combines Japanese craft gin with seasonal flavors and is meant to address his father's complex emotions. Impressed but stubborn, his father acknowledges the quality of the drink but insists that Chen return home and refuses to let him work as a bartender.

The discouraged Chen seeks advice from Sasakura, who encourages him to forge his own path and implies that true mastery and acceptance must be earned.
