She explained her first love in detail, saying, "When I first met him, he seemed nice so that made me think it'll be okay to meet him. There were cheesy and embarrassing moments, and we also saw each other's bad sides. [At first] I thought, 'Is it ok to meet him?' but when it was about 3 months, I found myself thinking, 'Is this love?' That was the first time I ever said 'I love you'."�

Lee Sung Kyung then compared herself to her character in 'Weightlifting Fairy Kim Bok Joo' and said, "We dated pure like Bok Joo. I've also never really had big crushes. I didn't open my mind to boys and always completely blocked them. I was shy and embarrassed. I used to hide my feelings, but now I'm honest."
