[Ancient Era] The Marquis's Wife Goes on a Rampage (Complete) Heroine: "You're the male lead's legal wife, but you're foolish and jealous and always holding him back. I'm talented and beautiful, and even the Noble Consort has taken me in as her sworn younger sister. I'll marry the male lead, Marquis Cheng'en, as his co-wife." Qing Xi: "Sorry, I've ruined the Noble Consort, brought down the Marquis Cheng'en's household, and killed the male lead. If you still love him, go join him in the afterlife." [Ancient Era] The Imperial Noble Consort Goes on a Rampage (Complete) Male lead: "I will make you a noble consort and shower you with affection. First, because your older brother is a powerful minister. Second, so my favor toward you can draw some of the attacks away from the heroine.

Qing Xi: "In that case, I'll ruin your kingdom, kill your heroine, and send you both to reunite in the underworld."

I'll take care of your wives. I'll help them become independent, self-reliant, and prosperous." Theme: The lives of supporting characters can be every bit as exciting.
