Grand Duke, It Was A Mistake!

I accidentally kidnapped the grand duke I have a one-sided love for!
I ended up accepting the grand duke’s proposal to have a contractual relationship in return for fixing this issue, but…….
“Vivian. May I kiss you?”
Huh? Are we kissing as soon as we started dating?
“We’ll kiss, then we’ll take things further, and then let’s get married, Vivian.”
……I’m in big trouble. I don’t think the grand duke is in his right mind……!
Is this relationship really okay?
