Ga-In teases Jo Kwon about Oh Bang Shil's identity

On a recent broadcast of MBC's We Got Married 2, the topic of Oh Bang Shil's identity was dug up again. Ga-In and Jo Kwon had received a mission to spend a vacation with one another. In order to stir up some jealousy, Jo Kwon decided to talk about Oh Bang Shil. He bragged, "I reunited with Oh Bang Shil at some music show." Ga-In coolly replied, "Are you talking about After School's Raina?." Jo Kwon became speechless, and Ga-In continued to tease, "Why do you keep making rumors out of things that don't exist?." Netizens have become interested and curious about Oh Bang Shil's identity, and they have been speculating that it may be Raina. Some pointers? Raina attended the same high school as Jo Kwon, and her real name is Oh Hye Rin. Also, Jo Kwon seems to show reactions whenever he hears After School's songs. Meanwhile, on this episode, Jo Kwon put on a couple ring event for Ga-In which displayed their affectionate status as a couple (?).
