Bound by Secrets: Her Billionaire DoctorEpisode 3

Five years ago, slum girl Luna was forced to jump by her wealthy mother-in-law Ellen and raised her son Neo alone. Now Neo has leukemia and needs a bone marrow transplant, reuniting Luna with her ex, top surgeon Ken. To protect her son, she hides her identity and signs an agreement with him—but Ellen and Ken's fiancée Tina scheme against her, causing a miscarriage and driving her to France. Ken uncovers the truth, commits his mother, jails Tina, and finds Luna again.
