Shen Jinyu is the iron-willed, cold-faced heir to the Shen family, decisive and ruthless. Behind all his glory lie countless secrets. Lu Wanning is an adopted son living under another family's roof. He seems gentle and refined, but he is a master strategist who plans several moves ahead. The two should have been strangers, but a marriage contract forces them to become "brothers."
Beneath the calm surface of the Shen residence, danger is brewing. Assassins infiltrate the estate, family conflicts erupt, and one conspiracy follows another. Shen Jinyu is deeply wary of Lu Wanning and sees him as a liability in his game of chess. Lu Wanning, meanwhile, advances step by step through every contest of wits, drawing others into his sway. The taboo surrounding their identities and the ties of fate gradually pull them into an emotional abyss from which they cannot escape.
The brotherly bond is only a disguise. Behind the marriage alliance lie family secrets and a massive conspiracy. Surrounded by external enemies and beset by internal troubles, are the two of them each other's salvation, or merely sacrifices in a game of political intrigue?
Amid clashing blades, love and vengeance intertwine. Will Shen Jinyu cast off his cold mask, and will Lu Wanning dare to give him his battered heart?
When the conspiracy comes to light and the truth proves horrifying, the choice between love and hate will tear everything apart. Are they each other's pawns, or the only home either of them can find?
