"In the entertainment industry nowadays, celebrity couples often consist of one strong and one weaker partner, each supporting the other's development. Neither is excessively strong or weak, but in your case with He Jinxia, you're simply too strong."

Reality is such a lamentable thing; not everything can work out perfectly.
