Han Yihyeon and Oh Taeoh go way back. They were best friends throughout most of their high school years…until one day, they just weren’t. Taeoh suddenly began to hide everything from Yihyeon, and try as she might, she could never find out why. Fast forward years later, when the two are young adults. Struggling to make it in the big city, Yihyeon returns home to live with her mother when she runs into her old friend again. Isolated from the rest of the world, Taeoh has not left the town - let alone his own home - since Yihyeon left. As the two grow closer once again, will Yihyeon be able to help lead Taeoh back into reclaiming a life of his own?
