Genius designer Catherine, upon receiving an invitation to further her studies at a prestigious school, was coerced by Damien's dying father, leveraging the life-saving debt, to marry Damien and devote herself entirely to helping him. However, Damien did not know how to treasure her, becoming entangled with Emily and wantonly trampling on Catherine. When Catherine decided to divorce him, he still imagined that this was her way of seeking his love, thinking she would soon return to ask for remarriage. Unexpectedly, Catherine chose to marry someone more worthy and returned to the pinnacle of her career. Meanwhile, Damien lost everything, ended up on the streets, and ultimately died tragically.
