The Unruly Husband

Zhang Junjie feels extremely sick after he finds himself in the novel he cursed at daily, as the main antagonist no less.
The novel 'The General Learns Wife Duties' portrays an ancient, mystical world, where the main character, a general became the spouse of a duke.
Even with all the attempts to break apart the couple, the main character and male lead's love only grows stronger and Nie Huifen, the second husband of Duke Jin Yuxuan is given the white cloth for his pathetic tricks to break the couple apart.

Junjie hated the male lead's guts because the man just sentenced the spouse who helped him rise in power to death for his new love. He found it sickening.

And so, while he is stuck he might as well save the antagonist from his sad ending
