Which special place did Alexander Lee visit while in South Korea?

With the success and high ratings of Alexander Lee's show, My Korean Jagiya, our Kapuso oppa takes a well-deserved break to South Korea. Aside from studying in university, did you know that Alexander used to be a radio jockey for TBS eFM's "Double Date?" 

While there, Alexander dropped by his previous radio program to catch up with his listeners and his co-host, Kevin Oh.

Before heading to the Philippines last July, Alexander left a long message on Instagram saying farewell to their listeners and the people he's worked with at "Double Date."
