On their fifth anniversary, Ethan Cole prepared a lavish dinner at home. However, his girlfriend, Sienna Reed, dressed up and went out, using the excuse of helping her professor with an experiment, leaving Ethan alone. Disappointed, Ethan accidentally discovered a collection of "sweet memories" — videos and photos — of Sienna and Damian Blake on her computer. Through their chat records, he learned that his girlfriend had even agreed to have a child for another man. Filled with anger and resentment, Ethan called Sienna to confront her, only to be mocked by her. Heartbroken and disillusioned, Ethan decided to break up. Just then, he received an offer from a top overseas company with a high salary. Ethan made up his mind to leave for his new job abroad in three days.
