Five years ago, Lu Chenzhou told Su Nian, "Get rid of the baby. We’re breaking up."
Five years later, she returns to the country with her three-year-old son and brushes past him at the airport.
He doesn’t recognize her.
Three days later, she is sitting in a meeting room at her new company when the door opens and he walks in.
His coffee cup crashes to the floor. He looks into her eyes and tastes regret for the first time.
"Su Nian?"
She stands up, her expression unreadable.
"Hello, Mr. Lu."
Later, he learns she is the new partner at his company.
Later, he learns the child is his.
Afterward, he tries everything to win her back, but she asks him just one question:
"Lu Chenzhou, have you ever regretted that phone call five years ago?"
