Me and my mind. I am trying to guess who he ends with by looking at their finger nails. There is a scene in the first few seconds where he back hugs him. This is a spoiler so don't fall for temptation if you want to keep the suspense.
For me, the sexiest scene will always be, when Hua Yong is fixing the clips holding the shirt on Sheng's legs and Sheng is just sitting there on the chair looking at Yong.
I read somewhere that in real life, the actor of Gao Tu, was mistreated by his previous agency and he suffered depression. During filming of Desire, his colleagues were always checking on him to see if he's ok. I hope he finds true friends to help him overcome his sadness and wishing him all the best for his future. (and wishing the right Karma to who hurt him).
