In the beginning, Su Xiaoxiao also guessed that Qin Hai was Qin Che's biological father.
It was not until she received the test results from the pharmacy that she came to a realization.

For example, why was Mother Qin so merciless to Ruan Xianglian and her son back then?
It was not strange that she did not like Ruan Xianglian, but Qin Che was her biological grandson after all. How could she bear to send her biological grandson away?
It would make sense if he was an illegitimate son born of a love rival.
Mrs. Qin would wish she could kill that little bastard, right?
Of course, the person Mother Qin wanted to kill the most was Ruan Xianglian.
