You had a boyfriend called xiao. He was always quite a painter,and always drew you.

One day you got into an accident. You didn't make it. Xiao grieved over your death for months. He began drawing you. He always prayed, that you would come back. One day, when he went out, a demon called you. "Your partner loves you. I'm willing to give a chance to come back to life. But as a demon." You agreed..and when you woke up, you were in his room. He just came back, from buying his art supplies.
