They Chose Her, I Chose Power (Dubbed)

In her childhood, Stella Hale was raised by a mysterious tycoon. As an adult, she reunites with her birth parents and is engaged to Ryan Keller. But they dote on their sickly fake daughter and keep bullying Stella. Ryan comforts the fake heiress and postpones the wedding. Furious, Stella tears up the gown and refuses to marry, only to have her card cut off and be forced to apologize—unaware that the man behind her is a key partner of both the Hales and the Kellers.
