Oh this is fun.
MC is just the right amount of evil, and ML is just the right amount of freaking ADORABLE! He is so cute I had to take a break because my smile was cramping. ML's a sexy walking pheromone that makes you shiver with his actions. I'm already simping. Hardcore simping. Also, when MC is forward ML's easily flustered which makes him the cutest!!!
Before Story Summary. MC woke up in a novel she read, as the fiance of one of the villain-extras (not even the main villain). The villain-extra has countless affairs and eventually, his behavior toward the novel's heroine causes him and his fiance the death penalty. Immediately MC plans to gather evidence of the villain-extra's affairs to break the engagement to crush the death flag, she also befriends the heroine to get in her good graces to live smoothly. Before MC gathers enough evidence of his affairs, that nauseating villain-extra decides to couple with the heroine and offers to break the engagement mutually. The heroine, who was MC's best friend, decides to steal MC's fiance... haha tr*sh goes well with tr*sh.
Now the story starts. MC proposes a revenge-affair deal to the prospective partner of the heroine (ML), and their story is hilarious. MC and ML meet upfront in person and in a guild behind masks, really funny how ML tries to command MC (with an infatuation power) to remove her mask. ML's ability doesn't fully work on MC, so I am evilly expecting ML to meet up with masked MC again to ask for relationship advice.
