Ji Suk Jin phoned Jin right away. Jin happily greeted Ji Suk Jin and Song Ji Hyo, and revealed he's currently in filming for something at Gwangju with his members. Jin also said, "Please call me whenever you miss me." To this, Ji Suk Jin and Song Ji Hyo 

immediately asked, "Do you have time today?" Jin seemed startled by the sudden invite.

Jin wasn't able to accept the invite on the spot but he might be making an appearance in the next episodes. 

Stay tuned!
