Reborn as the Demon King's Personal Bodyguard

A year after breaking up with my ex-boyfriend, I got into a car accident, and my memories seemed to become jumbled too. The things that happened before slowly grew hazy, while unfamiliar scenes flashed through my dreams, frame by frame, along with worlds that felt both familiar and strange... Reality and dreams intertwined until I could no longer tell them apart.

I seemed to be trapped in a dream, reliving the same one over and over. Who was the man in it? Why did my heart hurt so much? Why couldn't I stop crying? Who was he, exactly!? And what about me? Who was I!

I thought opening my eyes would bring me back to reality, but... What the heck! Did I transmigrate? Wait, where did I transmigrate to? What?! I'm supposed to protect the mighty Demon Lord? But, but I'm just a lazy fish!
