Yang Mi is always great but Xu Kai seemed to be sleepwalking through the drama. They had little charisma together. Or, rather, Yang Mi was giving everything she could but Xu Kai looked like he'd rather be playing video games. Relationships with big age gaps seem to work best when the younger partner is mature beyond his or her age, rather than when the older partner is immature for his or her age. I don't think Xu Kai quite pulled off the mature beyond his age role. And since this was all about the relationship, the drama fizzled. The remaining characters were not very likable either.
