girl just kill your father and forcefully take his throne

It's not even his throne. He's the consort.

so doesn't that make it easier or?...

Yup, she just needs to off him.

i think the prince consort came from a powerful noble family? thats why its complicated if she just straight up killed him. the empress will lose the power of that powerful noble family maybe???

This latest chapter had him use the little sister as a human shield. Smh
