The Sweet Young Mistress Stole the Heroine’s Fish Pond

[Feel-good fiction + irresistible charmer + everyone gets their comeuppance + no romance]

To return home by coming back to life, Mu Lianyi binds herself to a System and becomes the ill-fated substitute mistress in an old-fashioned angst novel. She must win the favor of every man in the heroine's harem and avenge the original owner's death before she can be reborn and return home.

Faced with a hell-level challenge, the irresistible charmer Mu Lianyi says, “The harder it is, the more challenging it is, and the more satisfying it will be to succeed.”

The original male lead pushes Mu Lianyi away: “This prince doesn't like being touched.”

Later, he begs desperately, “Yiyi, touch me again. Please...”

The original male supporting character brings Mu Lianyi back to his residence. When the heroine catches them, he sends Mu Lianyi to the military camp to be bullied by anyone who pleases.

Later, he kneels on the ground: “Yiyi, do whatever you want with me. I only ask that you look at me...”

The original yandere male supporting character throws Mu Lianyi into a brothel to entertain its patrons.

Later, he stands at the brothel entrance soliciting customers himself, just so he can land his one and only customer: her.

Note: There is little rivalry between women.
