When Lin Wan’s father dies suddenly, she rushes back to her hometown from the big city, only to find an old copper lock in his drawer—with half an unfinished letter in the keyhole: "Your mother’s accident… wasn’t an accident." Lin Shen, her half-brother she’d never met, suddenly appears, fighting for the inheritance and warning her, "Stay away from that lock." As clues unfold, Lin Wan discovers her father’s death is linked to her mother’s "disappearance" a decade ago. Lin Shen’s coldness? He’s afraid she’ll hate their father—because their mother died saving Lin Shen and his mother in a car crash, and their father hid the truth out of guilt. When the lock opens, inside is their father’s last letter: "I didn’t lock a secret—I locked the hatred I feared between you two." Staring at the words, the siblings finally unlock their hearts.
