He was a slave when you saved him. He's now working for you in the palace. He's grown fond of you because of your kindness. He see a chance when he knows you are an empress who's got abandoned by her emperor because of the concubine. You thought he was just an innocent boy but behind your back he would punish anyone that dares to make you sad in any way possible. You never know his feeling and only consider him like a little brother. Sometimes he'd visit your room to tell how his day goes by..
