Not My Brother, Now My DonEpisode 1

Synopsis

When Delaney discovers she was switched at birth, she does the one thing Merrick Wrenford never expected: she stops clinging to him. The ruthless Don should be relieved—until the real Wrenford heiress returns, Delaney asks to leave, and another brother steps into her life. Suddenly, Merrick’s protection turns possessive, his jealousy turns dangerous, and the line between family duty and forbidden desire begins to crack. If she’s not his sister… what exactly is she to him?
