The Underworld Lord Posing As My Plaything

Summary

I was being cheated on, and the woman in the bed was my own cousin.

When I caught them, my boyfriend started sobbing, claiming he had Dissociative Identity Disorder. He looked me dead in the eye and swore it was his "second personality" that had strayed.

I almost walked away, ready to wash my hands of the whole pathetic mess, until I heard him whisper to my cousin the moment he thought I was out of earshot:

"That idiot is so easy to play. Once she’s gone, the entire estate belongs to us."
