It's busy season and the office is filled with a murderous atmosphere. Hasegawa , who has just returned from a business trip, says that outside is a fireworks festival and the place is packed. Seeing everyone exhausted, Chief Okada treats them to pizza delivery and non-alcoholic beer. They all gather around the pizza and have a good time. The fireworks start and they watch them from the office window. Even though it's non-alcoholic, Ito-kun staggers around, which is comforting. Feeling refreshed, they can work hard. The next day, Mii-san, who has already left because she is pregnant, is a little depressed after hearing the story from Wakako and the others. She seems to feel left out. Wakako, worried, suggests a beer garden when the manager (Morishita Yoshiyuki) suggests going for a drink. Everyone gathers in casual clothes at the beer garden on the roof of the building. They drink draft beer in the middle of the day. Mii-san seems to be having fun. What did Wakako order...?
