At college, Vivian gave advice about picking up the handsome guy named William for her best friend, but no one knew that she's also deeply in love with him. After graduation, her best friend broke up with William and went abroad to get married and have a child. A few years later, her best friend announced that she was officially divorced and would return home to pursue her true love--William. By that time, Vivian had been living together with William for four years, but it was not the romantic relationship as everyone thought. They're just body mates. She felt that it was time for her to leave, so she secretly cleaned up all traces of herself and prepared to disappear. But the man pulled her and said to her, "I love you, and whom I want is also you!"
