As you all know, former girl group S.E.S got back together for an episode in MBC's Come To Play. Well, during this episode, Shoo apologized to g.o.d.'s Son Ho Young and Danny Ahn. Now why would she do that? As some viewers may recall, Come to Play contains a segment in which guests are asked to to answer questions brought up by the cast. In this Q&A section, Shoo was asked, "Using this opportunity, which star do you want to apologize to the most?" Shoo picked g.o.d.'s Son Ho Young and Danny Ahn. Shoo explained, "Before my debut as a S.E.S, I was training with Son Ho Young and Danny Ahn, as we were in a group that was going to debut. But when the offer to join S.E.S was brought up, I decided to debut first, leaving them behind." Danny Ahn, who was also present in this episode added, "We already had a title song but Shoo left."He then commented, "When S.E.S was on TV I was jealous, and I thought, 'maybe I should have followed her,'" which caused the cast to burst into laughter. Stay tuned to this special S.E.S episode of MBC's Come To Play, as it will broadcast on the 26th, 11:10 PM KST.
