I don't think so about Shindong, people "like me" are a non-factor in Korea, Shindong was added because he was actually really good at dancing, before Super Junior he has already won multiple prizes for that (including the 2004 Mnet Epic Contest (Gold Prize and Popularity Award)) and because SM wanted to put him on tv. His appearance was obviously a factor to SM bacause is different than any other member. At the beginning SM has put him on tv with childrens program and now you see him co-hosting programs and has already winned 3 (not fan voted) awards about his work on tv. When I talk about superficiality I mean that when someone see the boy/girl on tv she/he like them because of his/her phisical appearance, with Shindong the majority of people need to watch/listen to him on tv/radio to actually like him.
