I don't understand why oh why would i want to watch that actor in an idol historical drama, can cdrama stop shoving…
Beauty is subjective and varies from person to person. If you do not find him unattractive, that's fine but do not go under his drama pages commenting in such a vile manner like someone hurt you. If something is displeasing to the eyes, you simply avoid it. No one is forcing Liu Yuning down your throat. Feel free to go watch dramas that have handsome idol actors that suit your taste(oh, of which so many of them suck at acting by the way). Unlike you, so many of us out there find him extremely attractive and with his great acting skill, we willing to watch anything he is in. Now go touch some grass.
