The drama takes a stab at the rehashed switcheroo brides trope but still manages to give a refreshing take on xianxia. One sister, born under a lucky sign, gets to marry a heavenly prince, another one born under an unlucky sign gets to marry a demon prince. On the day of their wedding, they get switched and hilarity ensues as the drama develops two parallel love stories.

One thing that I really liked was a focus on sisterhood, family, and women working to uplift each other, instead of sisters and friends competing for men, money, and power. Although, the drama also rehashes a jealous side chick trope, it's very minor and pretty forgettable. I really liked the chemistry between each couple, as they got to know each other, develop bonds which led to love. I liked that the story blurred some lines between good and evil and allowed some characters with a questionable moral compass a chance to grow and make good choices. Chaofeng started out an an anti-hero, not entirely bad but someone with questionable morality. Through his growing love for Qingkui and exposure to her purity and goodness, he developed a conscience. Youqin gaining back his feelings allowed him to realize that protecting the heavenly realm wasn't just an arbitrary duty but a desire to protect family.

The plot was mostly interesting, but some arcs were better than others. I thought the shards arc was too long and kind of boring. My biggest criticism, after the shards arc both Youqin and Chaofeng were reduced to house husbands. Youqin spent most of his time waiting for Yetan to come home from school. It seemed like attaining the perfect celestial body was the pinnacle of his development and he had nothing else to do, although he was the most powerful being in all the realms. Chaofeng was told to look for work now that he had a wife. Twirling store signs pretty much undermined his position as a badass prince from the void. The writers could've come up with something better for immortal beings with ultimate cosmic power than this.

The acting was very good. Chen Xingxu showed his versatility where he didn't just portray a stony faced Empyrean Xuanshang, but a lover, a materialist, a pyromaniac, and a romantic. The character came to life as soon as he gained his feelings. Everyone else was just as good.

Some people were not happy with the ending, but I thought it was fitting for the xianxia genre leaving off the story on a positive and hopeful note. To me, that was a good ending.
