I'm the Villainess, but the Male Leads Are Winning Themselves Over

Lin Qiuzhi transmigrated into the body of a vicious supporting female character, and the original owner was destined to die in three days. She decided to rely on schemes to cling to life, but then... She set up the Seventh Prince, yet he admired her instead: "Ruthless enough. You're worthy of me." She used the intelligence network of the Crown Prince's tutor, but he stroked a wooden carving and chuckled: "So dependent on me?" She hired the world's greatest Sword Saint as her bodyguard, but he hugged his sword and snorted coldly: "...I'll protect you. For now." She coaxed a wealthy merchant's son into cooperating, and his eyes sparkled: "Big Sister really does love me most!" Lin Qiuzhi: "No, wake up, all of you! I just want to stay alive!" The male leads, in unison: "She loves us so much." (Female lead: Surviving through political intrigue; Male leads: She's so good at flirting!)
