This is a story about redemption, growth, and the true meaning of love. When two souls wounded by fate meet through an absurd boyfriend contract, they discover that real love is not about scheming or conquest, but about becoming each other's light in the darkest moments. One is Lu Chen, a mastermind of the Abyss who carries the mission of revenge; the other is Jiang Dailan, the lonely yet strong Iron-Blooded Empress.
