As star-crossed lovers 'Kim Ju Won' and 'Gil Ra-Im', actors Hyun Bin and Ha Ji Won kept viewers on the edge of their seats during the 10-week run of their wildly popular drama, "Secret Garden." But did you ever wonder what scene made Hyun Bin feel warm inside? Or what Ha Ji Won's favorite pet name is? Since their last episode aired almost two weeks ago, the stars have come forward with some of their own on-set "Secrets." In a recent interview with tvN's "On-Set Talk Show Taxi," Hyun Bin confessed that the show's infamous 'sit-up kiss' scene had more than just his abs burning: "To be perfectly honest, [the scene] made me feel a little weird and tingly inside." When the reporter asked if he was actually any good at doing sit-ups in real life, the actor shook his head and laughed. "Since I'm not a fan of sit-ups, I actually had a lot of NGs. I felt like I had to do hundreds of them." On the flipside, his "amazing woman" and co-star, Ha Ji Won also had a few confessions of her own. In an interview with "Star Today", she confessed that she loves being called "? ?~???? ???'??" ["You amazing woman"] -  a name that she often hears lately from her Japanese fans. The nickname first came about when Hyun Bin's character expressed his affection for her. Ha Ji Won even confessed that she was a little envious of her own character: "In the last episode, the couple have sons, but Ju-Won still only has eyes for his wife. Though it may be a girlish dream, I'm still hoping for that great love who will love me as his first priority." Although the show has ended, it seems as though the stars, their characters and the unforgettable ride that they took us on, will be one great "Secret" that we will surely want to keep.
