"Moon Lovers" couple reunites as Lee Joon Gi makes surprise appearance at IU's concert > K-POP

​IU held her 24 Steps in Taipei concert on January 7th in Taiwan and top star actor ​Lee Joon Gi ​made the audience gasp with his sudden guest appearance in response to IU's invitation.

Lee Joon Gi is in town for his own 2016-17 Lee Joon Gi Asia Tour ​meet and greet which will take place on January 8th and he made it just in time for the rare reunion between the two ​Moon Lovers: Scarlet Heart Ryeo ​main leads. The ​SBS ​historical drama was definitely a hit in 2016 and the two grabbed the Best Couple of the Year award at the SBS Drama Awards held on December 31st, 2016.

IU touched her audience with her near-perfect pronunciation in the singing of the drama's OST "Three Inches of Heaven", when Lee Joon Gi suddenly appeared on stage in a cape and the on-screen couple re-enacted the famous rain scene from the drama.

Lee Joon Gi will then continue his Asia tour, with Hong Kong up next on January 22nd.
