Mr. Walker, Your Ex-Wife is Your Boss

Emily Johnson, a hidden identity bestselling novelist (pen name Momo), marries CEO Ronan Walker but is neglected. She divorces after finding him "close" to actress Vivian. She returns to acting and meets producer William, who seeks revenge for Ronan's past accident. Misunderstandings clear: Ronan and Vivian are purely business (Vivian donated bone marrow for William's daughter), and Ronan always loved Emily. They reunite.
