NOT EDITED YET

Keon has too much hatred for his mother to investigate such a thing. Although he indeed know that his mother's reputation in the past was that of a kind, virtuous, and flawless moon

He along with the Duchess of Ybra were the flower of the society

The Duchess is kind yet also strongheaded while the Empress was kind and gentle at all times

Hence the reason why even though the two are top-tiers moon in their time, the Empress did not gold a grudge for the Duchess

If it was any other moon that is filled with jealousy, they might have started going against the Duchess already as they have to share the spotlight with him

However, the Empress aside from always having hatred for his own child is actually still kind and gentle to most people aside from the Queens and Imperial Suns and Moons

As such, even though the Empress largely changed in that part, the Emperor still loves him the same as before
