Both have the same Directors, Producer, and Costume Designer. You can see some of the casts of The Double in Perfect Match (Wang Xing Yue, Liu Xie Ning, Liang Yong Qi, Zhao Qing, Pan You Cheng, etc).
The Double is more about revenge and conspiracies, while Perfect Match is about the Li sisters finding their partners. YES, the plots are so different and I think that's the only difference.
If you love Wang Xing Yue's acting, I think you'll love this.
