Stella Sylvaine was the true daughter of the Tallien family, but she had been lost as a child. To revive her adoptive family — who had died in a car accident — she bound herself to a system and spent five years serving the Tallien family. Once she repaid her debt to her birth family, her adoptive parents and brother would come back to life. But the Talliens treated her with coldness and cruelty, believing she was only clinging to them. When the five years were up, Stella vanished before her birth family's eyes and returned to the people who had truly raised her. Only then did her birth family finally realize what they had lost.
