I don't know if each of SuJu's fans knows about this. So, I've decide to share about it.
As an information, Korea's Ministry of culture, sports and tourism was serious when they stated that they were in full support of spreading K-pop and Korea to the world! Since the statement was made, the ministry had done a lot of things in order to achieve their goal.
One of it is the release of the Seoul Song. What makes this song interesting is the singers are SuJu and SNSD and the MV is just like a pag-ibig story in one of beautiful cities in the world, Seoul. So, I guess it can be called as their latest song.
