Sister will be killed when one of her plots to kill off Blondina backfires.
And Lart gets with Lucy in the end and becomes the Emperor when his father abdicates.
The father prior will try to suck up to Blondina (which aggrevates Adellai more) because he finds out that Amon is an important Shinshu - he is their future tribe leader.
Blondina sees through this and does warm up or forgive her father.
She forgives Lart tho when he apologises and tries to make amends.
I heard they (Amon and Blondina) will have twin sons.
Oh and the 2nd ML isn't a nice guy. You find out soon in the next chapters, he is another arrogant aristocrat he sees himself above Blondina. And reckons because of her "inferior" background and lack of those who will want to associate with her.
He is a shoe-in to make her "his".
Because she is the one who takes most after the shitty emperor and is his favorite child.
Even Lart redeems himself later in the story.
Adellai never does. And the emperor only starts to be (fake) nice to Blondina because of amon (who is the future leader of the shinsu) being smitten with her.
Adellai misunderstands and commits herself into harming and destroying Blondina.
