All Four of My Ex-Boyfriends Are Crazy

Cen Xin's mistake was pretending to be the first love of a yandere. Several of her ex-boyfriends came looking for her, and her yandere boyfriend went straight into a dark spiral. In the last moment before losing consciousness, Cen Xin thought, If I get another life, I absolutely won't get involved with a yandere. When she opens her eyes, Cen Xin discovers that she's transmigrated into a book, and has a System. System: "Congratulations, Host, you've escaped your misery. Welcome to a new world. Please complete your mission: find your destined match among your four exes and achieve a perfect ending. Be careful not to let them find out you have other exes!" Cen Xin: "...I escaped one yandere and got four more?" When she's ignored, her gloomy yandere younger brother smiles. "It would be nice if we could be together forever." After Cen Xin beckons him over, the yandere younger brother turns into a cheerful, sunny boy. "Xin Xin actually came to see me! I should be grateful!" Jealous, the domineering CEO keeps a stony face. "Your cousin? Heh. Break up? Do you want to die?" After Cen Xin finishes taming him, the CEO licks her face. "Being your good boy feels amazing." The abstinent neurosurgeon spots the marks from her kisses and narrows his eyes. "What are you nervous about? Feeling guilty?" After Cen Xin gives him an earful, the doctor obediently massages her. "I was wrong. I shouldn't have doubted you." The wealthy illegitimate son, whose corruption level is naturally far higher than everyone else's, says, "Pick one: marry me, or die together." Cen Xin: ... Looks like she'll have to strike first. #The female lead has a fiery temper, no morals, and a hobby of sleeping. Everyone is obsessed with her. #A love-rival battlefield every day, men competing for her, yanderes are all her dogs, and every one of them graduated with honors from the School of Gentlemanly Conduct. #Pretty crazy, best enjoyed as a bit of fun. Theme: Love should be healthy.
