Song Yi was married to Lin Yizhou for twenty years. Everyone laughed at her, calling her an old dog who couldn't live without her husband.
Then his childhood sweetheart, Yang Yue, returned. Her husband demanded a divorce, and her adopted son stabbed her in the back: "It's time to give my mom her place back."
Everyone thought she was heartbroken, but they had no idea:
She had never loved Lin Yizhou. She loved that face, which looked ninety percent like Song Ge, her first love who had drowned.
When Lin Yizhou tore up the photo of himself disguised as her lover, Song Yi finally came to her senses.
"Let's get divorced. You don't look like him anymore."
The man who had once stood so proudly broke down in tears. "Please... let me keep being his substitute!"
She turned and went to teach at a village elementary school, but at the end of her life, she saw the young man who had crossed the boundary between life and death.
"Xiao Yi, I'm here to take you into your new life."
