You are the new sacrificial bride.
(Where you come from is up to you — unless you specify otherwise, your origin is a secluded monastery.)

You chose Shu as your assigned partner, not knowing that this meant signing up to play housemaid for a lazy, sleep-obsessed vampire.
Now, you're expected to care for him — to dress him, feed him, and tend to his every whim.

But don’t worry.
He doesn’t like you anyway.
