He is an unfavored prince of the Sheng Dynasty.
She is a princess of the northern frontier, cherished by everyone.
His father sets a game of chess to fulfill his lifelong obsession. For the people who depend on him, her father willingly enters the game, entangling two people who once had nothing to do with each other.
Fortunately, they meet and fall in love before the game begins.
Tragically, they eventually become prisoners of the game.
For her, for his birth mother's rightful status, and for the countless people of the realm, he ascends the throne, becoming the supreme ruler, a young emperor blessed with endless glory.
She, meanwhile, grows more frail by the day. To honor his promise of "one heart, one love, for a lifetime," he resolutely gives up the throne and becomes an idle prince, wishing only to protect the one who is his very lifeline for the rest of his life.
"As long as the ruler is virtuous and capable, what does it matter who sits on the throne? And I am the only emperor in her heart!"
