My Fiancé Chose My Sister – Episode 16

On her wedding day, Chloe learns her fiancé Arthur died in a crash—she once jumped after him. Reborn, she races to stop it, only to find Arthur alive with Mia, the fake daughter, while her parents helped him fake his death to marry dying Mia. Devastated, Chloe calls Ethan, whose old promise stands, and books the old observatory for her own wedding—no Arthur, no parents, but vows for two. Arthur thinks it's her farewell and shows up; Chloe exposes the lie, Mia's pregnancy claim collapses, Ethan's real identity silences them, and she marries him. She cuts off her family and rejects Arthur's apology. Three years later, in a small town, she meets a ruined Arthur and feels nothing. Choosing Ethan was the first time she chose herself.
