After the System Replaced Me, the Emperor Regretted It

After I failed to win over Lu Huai, the System took control of my body.

My body felt none of the seven emotions or six desires, and certainly wouldn't be heartbroken over him.

But Lu Huai went mad. He fell to his knees before me in a wretched state, asking over and over why I no longer loved him.

But I had died long ago. Now I was nothing more than a wandering soul.

How could a lonely ghost have so many feelings?
