The Junior Sister Hates Scumbags More Than Anyone

Ye Lingyou is a top assassin. Betrayed by her boyfriend, she was shot several times by him and her best friend, then died and transmigrated into a book. In this world, the original Ye Lingyou was also betrayed by the idol-like older sister she admired and her fiance. She fell into demonic ways and met her end with a sword through the heart.

The eldest senior brother is cold and aloof, with an air that warns people to keep their distance. As a result, nobody wants to talk to him much. The heroine wins him over, and he becomes her devoted simp. Ye Lingyou: "Eldest Senior Brother, where did your icy aloofness go? You've still got us! We'll hang out with you!"

The third senior brother is considerate and kind. Whatever the heroine wants, he'll do whatever it takes to find it for her. Ye Lingyou: "She's got money and a simp already. She doesn't need you at all."

The fifth senior brother is extremely possessive and often gets into fights with the heroine's simps. Ye Lingyou: "Fifth Senior Brother, look! She doesn't even have eyes for you!"

Ye Lingyou: The people I hate most in this life are heartless lovers, and even more than them, homewreckers and scumbag men!
