Crown Prince Cecil has wed Bertia, the self-proclaimed villainess. The two are now enjoying their happily-ever-after in what can only be described as the ultimate devoted love journey. 
However, their peaceful days are fleeting when Bertia's friend, Lysonna, reaches out with a special request-she wants Bertia to help plan her wedding. Still glowing from her own grand ceremony, Bertia eagerly travels to the Kingdom of Umyuve to reunite with Lysonna.
Still, something feels a bit... off. 
To her surprise, Bertia realizes that Lysonna is actually a character from the very novel she read in her past life-and worse, Lysonna was the villainess, notorious for tormenting her younger stepbrother and his fiancée out of jealousy.
Determined to protect everyone's happy ending, Bertia, once a top-tier villainess, makes a bold declaration:
"I'll step in as your stand-in villainess!" 
And so, the curtain rises on Bertia's new role as the world's first Proxy Villainess!

Because Prince Cecil is extraordinarily intelligent, life is boring for him. His days are without much excitement, but he becomes engaged to Bertia, the daughter of a marquis. The first thing she says to him when they first meet is quite baffling. She claims she is the "villainous heroine" in the story of his life!! According to Bertia, she has memories of her previous life. In a certain "romance game" she played in her life before, she played the character of the "villainess." Her purpose in her new life is to become an exemplary villainess and ruin the prince's engagement. In order to achieve this goal, Bertia does one outrageous thing after another and brings chaos and confusion into his life. A unique "love" story with a twist!!
