Taeyeon is one of Korea's most popular female artists. She's the leader of Girls' Generation, Korea's national girl group and has broken the record for first week sales by female soloists with her own solo albums. Taeyeon may be beautiful, talented, and successful... but she can't help but feel like she's missing something from her life... or someone. Someone that would make her feel less lonely when she's alone and more blissful when in a good mood. She couldn't put her finger on exactly what she was missing until Starlight, the second track on her 2nd mini album Why. Her collaboration with Dean had changed her heart and her life.
