Mù Qiānxún knew that Mu Xin didn't tell her the truth to protect her.
Even though she had a scumbag dad like Xin Liao, Mu Xin still didn't want to tell Mù Qiānxún the truth.
Because, by comparison, being an orphan was better than having a scumbag dad.
Now, the reason Mu Xin was revealing the truth was still to protect her.
If Xin Liao actually succeeded in claiming her as his daughter, with his shamelessness, Mù Qiānxún would have no peace in the Ou Family from then on.
Even with Ou Zun's affection.
Having a shameless, overstepping, thick-skinned father like Xin Liao would simply be the darkest shadow in Mù Qiānxún's life.
What's more, Xin Liao was undoubtedly someone who demanded endlessly.
The people of the Ou Family were well-educated, but when faced with an in-law who had no boundaries and lacked restraint, what could they do?
Mù Qiānxún couldn't be allowed to have infinite trouble in the future.
That's why this secret needed to be revealed.
