The Ultimate Female Singer

Teresa Chan inadvertently discovers that her daughter is increasingly resembling her best friend. Initially unconcerned, as she had raised her daughter herself since birth. However, one day, Teresa stumbles upon her daughter's medical report, revealing that her daughter has type B blood, while both Teresa and her husband are type O, making it impossible for them to have a B type child. Prompted by this, Teresa immediately arranges for a paternity test for herself and her daughter, which ultimately reveals that the daughter they had raised for 18 years is not biologically theirs. This realization leads Teresa to suspect that her daughter may have been switched at birth.
