Life is not determined by one choice, but by the persistence of countless days and nights after the choice. The reason why Su Xi chose the wrong person in her previous life was not because of "poor vision", but because she lost herself in the wrong relationship. She chose the right person in this life not because she had "opened her eyes", but because she had regained her own subjectivity.
Gu Yan deserves to be chosen, not because he is richer and more handsome than Yan Yan, but because he respects Su Xi's independent personality and supports her to become a better version of herself.
