Park Shin Hye's character, Gyu Won in Korean drama "Heartstrings", challenges herself to audition for the female lead role in the upcoming 100 Year Anniversary School Musical. In the 7th episode, former Broadway director Suk Hyun (Song Chang Ui) announces “love” as the theme for this year’s audition. After long thought, Gyu Won decides on “I Will Forget You” as her audition piece as it best described how she currently felt about Lee Shin (C.N. Blue’s Jung Yong Hwa).
Gyu Won sings emotionally and ends up tearing up mid-performance. Shin watches this teary confession nearby and appears to be slightly moved. A representative of JS Pictures stated, “Park Shin Hye was so into her character during the audition scene that she moved the rest of the cast and crew with her emotional performance.”
