Do Kyung Soo for the last couple years has been experiencing strange things. He's been seeing a girl that he's never met before, everywhere. He sees her in the mirror, in store front windows, in rain puddles, and even in people's eyes. He's never seen her in person only in reflections. Not only has he been seeing her but he has conversations with her too. Once Kyungsoo became apart of EXO she started showing up less and when Kyungsoo got worried she came back. This is the story about The Girl On The Other Side Of The Glass.
