Standing from his own perspective, he could see that the Shangguan Family was entirely unsuitable for An Xiaomian to marry into.
Back then, the Shangguan Family nearly caused An Xiaomian's death.
Now, even though the Shangguan Family has changed their attitude towards An Xiaomian and started treating her well, the Old King knows that those cunning aristocrats could suddenly be kind to Xiao Mian only because they knew Xiao Mian was a Princess and valued her status!
If Xiao Mian suddenly became an ordinary citizen and was no longer a Princess, the people of the Shangguan Family surely wouldn't treat her well anymore.
He is not only a grandfather but also a King.
The Shangguan Family once bullied An Xiaomian, and now he has already been merciful by not taking action against Shangguan Xiu's family, watching his once-bullied granddaughter marry into the Shangguan Family.
Thus, he would no longer have the face to meet his first wife and his son in the future.
