The Boss Proposed To Me

In order to save her mother's life, Leanna sold her virginity to a CEO. But it was actually a fake deal which made her lose everything.
Four years later, she returned to the city with her son, opened a florist and met that man again.
As they met, her son asked the man, "Sir, do you want any flowers?" Trystan said, "Yes, I'll buy for your mom." The next time they met, her son said, "Sir, you bullied my mother, so you must treat her on dinner." "Okay." To Trystan, all women were troublesome, except for Leanna. He loved her and would gave her the best.
