What's the situation with House Leight?

Summary Obviously, the Xian Alliance has now been dissolved.
10 years... that's a long time for a partnership.
We agreed to overlook their transgressions
in exchange for the acquisition of all their shares.
Thanks to you,
the Keplan trade rights you secured for Elina now fall to us.

Summary Well, for starters,
I'll do my best to ensure my father wins the upcoming election.
And I'll be running for a seat on the Kalis Parliament as well.
That trial really helped me gain a lot of support from the citizens.
It could be the first time in the republic's history
that two council members hail from the same house. All thanks to you.

Summary I only agreed to the engagement because of my father's insistence.
I never planned to actually marry the man.
Besides, thanks to you, our family's standing isn't as precarious as it once was.
We no longer need the facade of House Erne.
But... I suppose I'll have to marry someone eventually, right?
Hmm... "the hero of Calpheon" would be quite the political asset...
Ah, I'm teasing you! Hahaha. Don't take it too seriously—
What? No— really! Have you never heard a joke before?!

Summary Yes, it's a special promotion! You're the hero of Calpheon, after all.
The rookie status doesn't quite do you justice any longer, does it?
Oh, don't worry about my father or me.
We've arranged for you to run the Calpheon branch independently.
Povios NPC Knowledge will be there to support you. He might not say it,
but he respects you a lot. Don't worry.

Quest Text How was the banquet? I made sure everything was perfect
for the new head of the Xian Merchant Guild's Calpheon branch!
