The owners are back this winter to run a store again. Since they've experienced running a store last winter, they head to the store in confidence. However, the store they will run this time is beyond their imagination. Not to mention the size, they need to run a meat shop, make deliveries, and even go to the market to fill in the items by themselves.

It is Day 1 of the business with the part-timers. Kwang-soo is unexpectedly good at taking the counter, and Woo-bin is busy trying to help everyone. Ju-hwan takes care of the meat shop as the Meat Master. In-sung gets nervous as people come to have his food, and Tae-hyun goes out to make a delivery.

In-sung was acknowledged as a good cook when he ran the restaurant last year. However, he becomes flustered as his dish gets complaints. Ju-hwan is in charge of a new dish, and Tae-hyun learns how to prepare meat. Woo-bin and Kwang-soo go out to make a delivery. Meanwhile, In-sung prepares a special dinner for the members.

Ju-hwan's deep-fried shrimp gets a great response from the customers. The members get surprised by his unexpected cooking skills even during dinner. The supermarket goes through another busy day and the members get familiar with more of the people of the area.

Woo-bin and Kwang-soo make breakfast for the other members. However, they need to do some research before cooking since they've never cooked for others before. In-sung comes up with an idea to prepare the broth for the next day. Tae-hyun is busy working at the meat shop and making deliveries.

This is the last dinner with Woo-bin. Since Woo-bin is leaving, In-sung cooks a special dinner for him. One of the customers does a surprise event, and Tae-hyun asks Kwang-soo and Ju-hwan to work a day more. Meanwhile, Tae-hyun and In-sung go to buy products, and new part-timers come to the store.

The New day begins with new part-timers. Two experienced and one rookie part-timer arrive at the store in the morning. Shin Seung-hwan looks for delicious foods as he's the official glutton. Yoon Kyung-ho checks and organizes the items in his own way. Park Hyo-jun prepares a special dinner menu for the customers.

Seung-hwan leaves after showing his charm as a glutton. Seolhyun joins as a part-timer. It's her first time working at a market, but she gets the hang of it faster than expected. Tae-hyun goes to Gwangju to fill in stocks, and In-sung and Hyo-jun make a new menu for lunch.

Actor Park Byung-eun comes to the store as a new part-timer. Since he has appeared in the first season, he knows what to do just by glancing at the store. He brought a yellowtail from Jeju Island, and he prepares yellowtail sashimi for dinner.

Byung-eun is in charge of the meat shop today since he's good with knives. However, the meat shop is rather free today, and Byung-eun becomes a chatterbox. In-sung and Seolhyun come up with a new menu. Meanwhile, a group of customers makes the members frustrated.

The owners are nervous in the morning as they wait for the new part-timer. Today's part-timers are Kim Hye-soo and Park Gyeong-hye. Though Hye-soo has no experience in working at a store, she gets better while showing off her unexpected charms. Meanwhile, another surprise guest appears.

Chef Jo comes up with a special menu for dinner service. It's zucchini pasta with pollack roe, but he makes mistakes as he's in a hurry. Gyeong-hye gets used to taking over the counter, and she even learns how to cut meat at the meat shop. Meanwhile, Hyo-joo makes a special dessert for the customers.

It's the last day at the supermarket, but the owners and the part-timers are busy as usual. Hye-soo almost makes a mistake, and Tae-hyun becomes a master butcher. Tae-hyun's friend, Hong Kyung-min comes to the supermarket and sings for the customers.
