Su Wan's love letter when she was eighteen years old was exchanged for Lu Yaosheng's sentence of "not overestimating one's abilities".
Seven years later, he handed over a marriage contract to save the Su family, and she got married like a moth to a flame.
She was three months pregnant when she saw him blocking a car for Bai Yueguang, and blood stained the stars in her eyes.
Five years later, she appeared at a charity dinner holding a boy who looked like him.
Amid the uproar, Lu Yaosheng knelt down and held out the ring stubbornly: "I opened your love letter when you were eighteen years old, ten years late."
"Now I will spend the rest of my life paying you back, okay?"
