Ryu Jeongseok

Male 40s / Architect A famous architect who has even won international design awards. He runs the Ryu Architecture Office in Cheonghae and lives with his son, Bohyun, as a divorcee. Contrary to his handsome, middle-aged appearance that makes people fall for him at first sight, he has a prickly personality and a blunt way of speaking centered on hard truths. He fell in love at first sight with his classmate Yeojeong, married her, and went to study abroad in Germany together. He supported her so she could focus on her studies, but they eventually split, and he returned to Korea alone with Bohyun. In the past, Jian was like a stalker disguised as a pure-hearted girl who chased Jeongseok around, calling him her first love. He meets that Jian again more than 20 years later. Just like that, clutter and bustle begin to seep into Jeongseok's daily life. As he discovers the same sorrowful girl still inside Jian, the warm and affectionate boy that was still inside Jeongseok begins to wake up. In the heart of a man in his 40s, a boy's pure devotion begins anew!

Ryu Bohyun

Male 20s / Jeongseok's son, Flower Farm Operator The undisputed center-visual of the young farmer world and a sunshine-like presence in Cheonghae Village. He inherited a tsundere streak from his father, but his temperament is a bit warmer, making him weak to the requests of the village elders, especially Grandma Mimi. Growing up, Bohyun naturally became accustomed to loneliness as he watched the gap widen between his mother and father, becoming a child who enjoyed being alone. Now, he is a seasoned farmer in his 6th year. His curiosity about Hyori, a girl with many stories, keeps nudging his heart. He tells himself to be careful and not get involved... but being a bit of a meddler by nature, he can't stop worrying about Hyori. As he does, Hyori—who is similar to him in some ways and so different in others—begins to grow in his heart like a weed that keeps coming back no matter how many times you pull it. Like a firefly in late summer, a coincidence becomes fate, and something sparkling begins in Bohyun's heart!

Kim Soyeon

Female 20s / Flower Farm, Specialty Crop Cultivation A successor to the farming business. It's not that she couldn't study; she chose not to. Why? Because she had the ambition to inherit her parents' land early on and farm properly. She is a woman of the earth. Her personality is a bit prickly and blunt, but she is honest, doesn't hold grudges, and is the cool type who would rather swear to your face than talk behind your back. She likes Bohyun and was strategically putting in effort to win over the 'Iron Wall' man, but Hyori's sudden appearance causes a problem in her plan. She thought a love triangle would form between her, Hyori, and Bohyun, but as time passes, it somehow turns into a triangle of friendship.

Yoo Dongseok

Male 20s / Restaurant The youngest son of 'Dongseok Butcher Restaurant' at the entrance of the village. Though he received less attention from his parents because of his older brothers, he grew up well on his own. He is good at butchering meat, making deliveries, and helping out at the shop. Lately, he often helps Bohyun with the flower farming. He has been destined best friends with Soyeon and Jaedong since they were in their mothers' wombs.

Lee Jaedong

Male 20s / Onion Farming A young farmer responsible for a 2-hectare organic onion field. He looks like a hipster but is serious about farming. He is the hardworking type who helps with Bohyun's flowers and Dongseok's restaurant without hesitation. He has spent his entire life with Soyeon and Dongseok. Growing up side-by-side, the three of them became friends who know each other best.

Lee Sook

Female 20s / College Student Hyori's best friend who can communicate with her just through eye contact. Even for her, who is bright and optimistic, there is a natural enemy: Hyori's mother, Jian.

Kim Sunyoung

Female 40s / Construction Site Restaurant Owner Jian's loyal best friend and the owner of a construction site restaurant. Known as "Chef Kim," her food is second to none. With a simple personality, once she distinguishes between enemy and ally, she gives relentless trouble to the former and unconditional loyalty to the latter.

Yoon Taeo

Male 30s / Surfing Club Operator A hip, free spirit and the hippie guy of the seaside village. When you see him surfing in the ocean, he looks quite decent, even cool. But the moment he opens his mouth, you'll tilt your head in confusion. He is a restless, clueless energizer. After wandering from place to place, Cheonghae was where Taeo finally settled down.
