I Seduced the Deceitful Duke

I am a capable guild member. My mission is to disrupt Duke Berry Winter’s wedding…
“This marriage can’t happen…because I’m carrying the blood of a duke”
The wedding ceremony began to stir under my words. If the situation continues like this, the wedding ceremony will be over soon, so should we withdraw early?
I was about to run out of the wedding venue. But Duke Berry Winter approached me again and said.
“Honey, why are you so late?”
Honey? Is he calling me honey?
“It’s almost time for me to actually get married.”
“…?”
“If that’s the case, our children will be disadvantaged.”
Wait. Is this the first time we’ve met?
