I think it's been cancelled or postponed; a synopsis was on Viki's site but is no longer there. Oh Man-suk is currently starring in "The King's Family" on KBS. Yoon Sang-Hyun is currently (as of November 2013) shooting a movie in Korea called "Five Siblings in Deoksu Village".
I actually found an update on HanCinema. http://www.hancinema.net/korean_drama_I_Love_You_v__Mister.php
i went to youtube to search for this drama, when i typed in the title all i got was this portugese subbed movie mi amado, ahjussi (my beloved ahjussi) it stars ha ji won and yeon jeong hun.. there was no eng sub but i patiently finished the movie..
and yes i can't find it anywhere either.. except on viki.com though, it's just that my country is not allowed to watch it and the page is under construction.. when it's okay i hope someone tries and tell us all about it... :)
Sadly I don't think this is a yaoi *sadface*... I think this is just a really new drama that hasn't been updated yet. I think it's just about a guy who once was an idol, got into a coma and now wakes up 17 yrs later as an adult I guess or something....sounds like it XD
