Born as the illegitimate third son, the Joseon king forced his way onto the throne through chaos and bloodshed. Now, as his rule begins to spiral and the kingdom edges toward collapse, the only person he finds comfort in is his childhood friend, Sam-myeong. But what once was simple affection has slowly transformed into something far more dangerous. The king’s attachment grows into an all-consuming fixation, and he becomes willing to use schemes, manipulation, and even force to ensure Sam-myeong never leaves his side.
