In a recent recording of SBS's 'Protect the Boss', Ji Sung and Choi Kang Hee filmed a scene that involved a romantic back hug while he asked her out on a date. The scene was filmed inside an elevator, and in order to avoid being caught on CCTV cameras installed in the ceiling, Ji Sung hid behind Choi Kang Hee and shyly pulled her into a hug.  Once the doors actually opened, however, they were discovered by chairman Cha and secretary Jang, causing Ji Sung to accidentally shove Choi Kang Hee away.  Hilariously, she ended up being pushed into chairman Cha's arms. The chairman nonchalantly replied, "You guys can continue whatever you were doing!" Producers stated, "It's an important scene that really brings forth their love line to the spotlight.  At the time of the filming, fans of the drama showed up to give their support, so the set was lively and energized."
