The delinquent Choi Young-hyeon and his personal toy, Lee Min-woo.

Min-woo had always obeyed Young-hyeon without protest, swayed by the delinquent’s ever-changing moods.

But one day—nine years after it all began back in middle school—Young-hyeon abruptly declared an end to their relationship. And in doing so, he overlooked one crucial fact.

That the “personal toy” wasn’t Min-woo at all—it was himself.

A truth he realizes only after waking up in a strange room... kidnapped.
