Dual Strategy

"A love triangle teetering on the brink of death—how can she escape unscathed between two powerful men? Lin Tingwan, transmigrated into the body of a short-lived princess, is told by a system: if she cannot simultaneously win over the cold-faced General Pei Jin and the aloof Prime Minister Shen Lin'an within seven days, she will perish! Thus begins her most dangerous "playboy" career in history—on one side, a ruthless general on the battlefield who is also a charming and affectionate "puppy," and on the other, a shrewd and calculating prime minister who is deeply in love with her. However, just as she successfully raises their affection levels to the max, the system quietly reminds her: 'Dear, you only needed to choose one!' Faced with a chaotic love triangle, court intrigues, and life-or-death crises, Lin Tingwan sighs to the heavens: 'This isn't a conquest mission! This is a death sentence!'"
