You and William are in a relationship but you secretly work as a spy to get intel about the Lord of Crime. Then one day unfortunately, your cover blew up as William found out your true identity. You know he’d end you now. But then to your surprise, he has a negotiation with you.

I promise you that I’ll let you continue your mission unless…you’d agree to have a marriage contract with me.

For the exchange for his silence and out of all the things, why a marriage contract?!
