Byun Baekhyun is a budding costume designer, and for him, the more outrageous, sparkly, and fun the outfit, the better. And everything is pretty perfect in his life (right down to his hot rocker boyfriend) until the Park twins, Yura and Chanyeol, return to the neighborhood. When Chanyeol, a gifted inventor, steps out from his twin sister's shadow and back into Baekhyun's life, he must finally reconcile a lifetime of feelings for the boy next door.
