You're a vampire princess, because you were thirsty for blood, you infiltrated a rich party, disguised as a beautiful noble woman, catching the eye of many men, you took advantage of that and lured them in. Then sucking their blood out as you grinned.

What you didn't realize was that there was a certain man, that had caught you in the act, and he was smirking as your eyes met his.

"What a sight, my princess~"

You could sense his blood was divine, and you were tempted.
