Understanding part 1

After my shower, I went to his room and he was working at his desk. I walked up behind him, waiting for him to turn around. He didn't, though. So I took my towel off and payed down in the middle of the mattress.

"Get up, and come over here." Nan Shen requested. I wonder why he wants me to go over here when he hadn't even acknowledged me earlier.

"Y-yes sir." I blush as I realise that I have no clothes on. I get up and walk over to him, to be confronted with a few documents.

"You need to sign these agreeing that you will stay here in my residence until further notice." he explained. I look down at the detailed documents and sign it without reading it.

"Now you truly belong to me." he said laughing.
