Byun Baekhyun and Jeon Iseul. Two broken people. Two different paths of known strangers for not crossing it ever again. But what happens when their paths are destined to be crossed? What happens when they are shown to different realities of the believed facade around them? What happens when their paths lead to the same destination of theirs?   And what happens when their darkness welcomes the daylight in their chaos of hearts by being the warmth and peace for each other?

Lost ones are sometimes found back again. Like the bond they shared was found back through the decade of their yearning but could a lost love be found again? Without the interruption of their wrong timing again? Join their tale of unforgettable us.
