After marrying into the Wei family, Regina swapped her newborn daughter Seraphina for a boy to secure her status, later inheriting the fortune with him. The infant was given to Cynthia, who abandoned her after taking the money. Seraphina was raised by a kind scavenger. Two decades later, William—the Wei heir—met Seraphina by chance. Touched by her devotion to her adoptive father, he married her, unknowingly reuniting with his long-lost sister.
