Chu Yan was already pregnant with Shang Qing's child when she left him.
If she hadn't accidentally discovered the truth he was hiding, what awaited her would have been a grand wedding.
Shang Qing had long known he had a daughter.
Lu Xining would never believe that someone as meticulous as him wouldn't arrange a paternity test after meeting his biological daughter.
When he publicly announced the return of his daughter, it meant that Shang Yueling had successfully passed the paternity test. Back when Lu Xining first heard the news, she thought Shang Yueling was Shang Qing's daughter with another woman and didn't give it much thought.
But later, she overheard that Shang Yueling's mother was Chu Yan, the eldest daughter of the Chu Family who had vanished for over twenty years, and an uncontrollable fury welled up within her.
Her mother only ever had one daughter — Xining herself — and she knew this better than anyone.
