Heechul one day decided to surprise Jae Jin on a show called Strong Heart, where he came as a guest. He told the two MC's, Kang Ho Dong and Lee Seung Gi that he wants to sing for someone. Eventhough it was an impromptu performance he knew it's for her. Dedicated for her. 

The song he sang was titled: Because You're My Girl Lee Seung Gi's debut song. The audience were amazed of how passionately he plays the piano. 

After his performance he told the audience "The song that I sang was dedicated for the woman I love. Saranghamnida Jae Jin." He smiled at the camera. 

At home, Jae Jin was watching it live and she felt her heart about to burst. She had happy tears in her eyes as she watch Heechul interact with the other idols on the show. She was happy he'd do it for her. She knew how much he really mean to her and how she loved him very much and they hoped that they'd be together until the end.
