This is one of the most popular and captivating Bl series out there. However, if you are into romance developing then you should stay away from it. I for one could not get myself to like this drama no matter how many times I watched it. It is honestly an abusive relationship, all that the Master sees of Nian is a toy that he got at the orphanage and a toy that deserves to love him and satisfy all his pleasures to show gratitude. Even though the master shows some compassion in some ways, he is short tempered and throughout the movie, he is basically abusing Nian having mutual feelings like him. I would recommend it for some people, but it's not my cup of tea as the whole movie at times made feel uncomfortable or sympathetic towards Nian.
