Park Shin-hye claimed that she and Jang Geun-suk were like brothers and sisters to each other. They were only friends, despite the fact that they enjoyed spending time together. She also said that Jang Geun-suk never regarded her as a female, preferring to treat her as a younger sister. Surprisingly, Jang Geun-suk confessed to being in love with actress Yoo In-na. This makes Park Shin-hye feel sad because she had always wanted them to be together. They met on the set of a movie called "The President's Last Bang" where both Jang Geun-suk and Yoo In-na played roles. After shooting was completed, Jang Geun-suk invited Yoo In-na over for dinner at his house. During the dinner, Jang Geun-suk told Yoo In-na that he was in love with her and asked if she would marry him. Yoo In-na replied with a smile that she would think about it later after talking to her family about their marriage proposal. The next day, Jang Geun-suk sent Yoo In-na an email saying that he had decided not to get married after all because it was not what she wanted. This made Park Shin-hye feel bad because she had always wanted them to get married. Later on, Jang Geun-suk went to Japan to work on a movie called "Gunslinger Girl". While there, he met with actor Takao Saito who was also working on the movie.
