Originally a 21-year-old medical student from the year 2060, Song Chuman is reborn as a six-year-old girl in a fishing village after being drowned during a sacrifice to the Sea God Madam. She is pale, feverish, and weak when she regains consciousness on the shore, but she possesses a mysterious system that allows her to modify one word in the plot at a time, with the ability to upgrade. Using this power, she alters her uncle's action from chopping firewood to attacking her grandmother, saving herself from being thrown into the mountains. She also develops psychic abilities that let her detect seafood buried in the sand. Despite her young age, she is clever, determined, and fiercely protective of her family. She pretends to be a normal child but uses her knowledge from her past life and her system to improve their poverty-stricken living conditions, planning to dig for seafood and sell it in the city. Her courage and resourcefulness make her the key figure in her family's struggle against the cruel Old Song family and their superstitions.
