But she was given a chance to come back to life. System (pointing at the male lead’s photo): This is your target for this mission. Got it? Jiang Qingyue (panting excitedly): Leave it to me. A gorgeous guy like this? I’ll sleep with him first, then kill him. I won’t hesitate when the time comes. System (rolling its eyes): You’re supposed to win him over! Jiang Qingyue (screaming like a lovestruck beauty): Leave it to me! I’ll get the job done! System (looking pleased): Within three days. Jiang Qingyue (stunned): WTF? - Chu Mishi was born with a death sentence hanging over him. Time until death: three days. He stayed holed up in a dim little room, waiting for the end. Then a girl suddenly pushed open the door and said she was there to save him. - The first time she met her target, Jiang Qingyue confidently said, “Hi~ I’m your wife.” Just as you’d expect, she died. Her target stabbed her to death. - Jiang Qingyue was killed by Chu Mishi again and again. Time reversed again and again, and she started over. At first, she desperately tried to make Chu Mishi fall in love with her so she could earn her chance at coming back to life. Later, she was determined to save him. She wanted to hug the boy who had never felt any warmth from the world. - This summer, I’m going to make A-Mi fall in love with me.
