This news comes to us courtesy of Yu Bo's EClub (thank you wjjing).
SYDT is scheduled to air soon. Apparently it will air in Korea (韩国 is Korea, right?) in Jan. And the station that will air SYDT first in China will be a station in Hang Zhou. It will probably begin airing in Hang Zhou on the 2nd of Feb. Promo events for SYDT will be held in Hang Zhou on the 2nd and 3rd of Feb.
According to someone from Ada's EClub, the lastest news coming from HK is that Ada will be unable to attend these promo events.
Also, from Ada's EClub, the series has begun renting in parts of China and early word is that it's pretty good so far.
So keep your eyes peeled. It'll be little while more before it hits the international market but it should be soon.
