Lee Sia is the mother of Green and Grim and the CEO of the eco-friendly resource circulation platform company, GreenGrim. From her childhood to the present, she has lived every moment with excitement and passion. Born and raised in Jeju as the youngest of four sisters, she grew up under the influence of her mother, who has been running a flower shop for 50 years. She has always been interested in life forms such as flowers and trees. Next to her mother's flower shop is a café run by her sister, which led her to contemplate the waste issues from the many cafés that open and close. As a result, she discovered PLA, a biodegradable plastic alternative to petroleum-based plastics, and even flew to Shanghai, China, while she was pregnant, driven by the urgency that she had to pursue this mission now or never. A week after her visit, the COVID-19 pandemic broke out, and the world began to focus on the problems of disposable products. With her foresight, GreenGrim was founded at the perfect time and has since been transforming café culture across Jeju and Korea.

Gilsu and Seokbeom have been close friends since high school, where they were both soccer players. After grueling training sessions, they found solace in listening to music together through shared earphones. After graduating and leading separate lives, the two decided to join forces with their wives, Hyeonji and Yeoreum, to create their own paradise in Jeju. This paradise is a self-service LP cafe called Romi Music House, where visitors can select and listen to LPs themselves. On clear days, they hold a special event called "Blackout Time," where they turn off all the lights after sunset and play music. They also plan fun and fresh pop-up stores with other shops. Romi Music House is Jeju's first solo LP cafe and the first in the country to host "Blackout Time". In less than six months since its opening, it has quickly gained a reputation as a hot spot.

It has been eight years since she came to Jeju on a whim to help her sister. For the first year, she spent her time solely on the guesthouse, household chores, and taking care of the children, feeling depressed and lonely. Then, following her sister’s suggestion that the pretty seashells on the nearby Hadori Beach might provide a clue to her life, she began taking walks on the beach and realized the beauty that nature offered. Picking up seashells gave her hope that she could create something, and she reinvented herself as the "Sold-Out Queen" at the famous flea market held at Sehwa Port, leading to the start of her own accessory shop, "Dallang Jeju." She is also active as a member of the organizing committee for the village-led Momo Flea Market and works as a professional environmental instructor specializing in climate change in Jeju.
