Quick Transmigration: The Alluring Beauty Who Captivates Everyone

[Quick transmigration + love triangles + regret after losing her + male rivalry + no fixed couple + the heroine is tormented early on, the men later] Fair-skinned and beautiful, Wen Rumian is a captivating woman adored by everyone. After an accident sends her into a mission, she becomes a despised female supporting character. The worst part is that high-difficulty missions keep popping up from time to time. She has to reform the major villain? Win over the original heroine's four suitors? Torture, inside and out? Get crushed by the original heroine? Become a sacrificial extra? Not happening! Male lead? Villain? Male supporting character? Wen Rumian curled her lips into a smile. “Are you ready to become my devoted admirers?” For the sake of her missions, she leaves each small world by faking her death, enjoying physical intimacy without giving her heart. World One: A possessive CEO switches identities with his younger brother and toys with her feelings. Her former fiancé insists on breaking off their engagement, claiming he loves someone else. Her unrelated-by-blood older brother turns away coldly, ignoring the danger she is in. But after she reforms them... The possessive CEO clutches her and weeps. “Rumian, I was wrong. It was my fault for using you.” Her obsessive younger brother, eyes bloodshot, kneels before her grave and apologizes. “I let you down. I'm a monster.” Her former fiancé regrets everything. “I shouldn't have insisted on breaking off our engagement. I ruined your life.” Her proud, cold older brother loses control of his emotions. “I'm sorry. When he bullied you, I failed to protect you.” (Not a conventional feel-good power fantasy. The heroine is a silly, laid-back fake do-gooder. Please don't read if that's not to your taste.)
