On the January 13 installment of SBS's 'Roommate,' Sunny talked about the dating experiences she had since her debut while talking with Lee Kuk Ju and Nana.  

She was asked, "Have you ever dated since your debut?" and grabbed attention with her surprising question, "What kind of dating?"

When someone asked back, "Are there types of dating?" she replied, "There are serious relationships and relationships you try out lightly."  Nana and Lee Kuk Ju were clearly engaged as they could only stare at Sunny.

They asked, "If you combine this and that, how many times have you dated?"  Sunny replied teasingly, "Must those be counted childishly?"  Surprised, Lee Kuk Ju and Nana responded with exclamations, such as, "That's amazing," and, "I'm jealous."

Sunny continued, "But you can't get caught.  By the public.  Oh, I'm being filmed, right?"
