Ella then framed Isabel and snatched away their eldest son. This also caused a misunderstanding between Isabel and Winston, leaving Isabel to raise the remaining three children alone. Six years later, in order to seek treatment for her youngest son's illness, Isabel had no choice but to bring the children back to Winston's side. There, she encountered a son who was identical to their elder son. After years of entanglement, will the two of them be able to clear up the misunderstanding and reunite?
