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?
