Miss Demon King, Please Just Give In and Marry Me

Five years ago, the demon princess Enora spent a fortune at a slave market to buy Xia as her maid. She never could have imagined that five years later, her former contracted maid would lead her by the hand into the wedding hall. Though, it seems... she's the one taking the initiative.

Enora (looking a little flustered): Wait, Xia, aren't we moving too fast? I don't think I'm ready yet. Could we...

Xia (looking smug): I'm not letting you run away, my dear "Master Big Sis."
