Since both boys could remember, their lives were one in the same. Some people consider being telepathically bound to someone a gift. Not for Hongbin. He hated every second he was stuck with Taekwoon. His life wasn't his own. Taekwoon, on the other hand, had loved having that mental connection with the young male. They were a few years apart in age, but that hadn't bothered him. His younger counter part took place of the younger sibling he never got to have since he himself was the youngest of four kids. Hours upon hours of the elder's time went into research on how this peculiar bond may have come about. All that research was for nothing. One day, both of them awoke to find that their bond had somehow vanished.

A year has passed and they've moved on with their lives. Hongbin is plagued with images of the man whom he once shared his entire life with. Taekwoon has spent the past year struggling with the decision as to whether or not he should seek out someone who seemed to hate him whole-heartedly. When one of his sisters moves to the part of Seoul that Hongbin was last known to be living in, the elder of the two moves in with her and begins his pursuit.

Will meeting in person be their final undoing or bring the two closer together than before?
