Do not get me wrong I really loved this show, but I was really put off by how much the show reiterated that Yi Jae needed to be punished for his decision. I think that it has to do with the fact that this show was sponsored by the Korean government like the sports and culture I think. Korea is known to have high rates of suicide due to work culture (not only Korea). I understand the messaging of finding purpose and wanting to show there is good in life, but actively punishing someone after they have made a decision to literally die and feel guilty is not really beneficial. As a person who heavily identifies with Yi Jae it made me really uncomfortable.
Despite this I found the acting in this drama to be absolutely amazing and it really evoked strong emotions in me. The last body he takes made me BAWLL!! I totally forgot that it was not Seo In Guk playing all the different characters, it really felt like he was just wearing their faces.
The story line was also really interesting, I personally have always wanted to be able to live in another person's body so it was really fun and interesting to see how the director worked with the plot. Also the fact that there is another plot that Yi Jae is solving aside from his death was also really cool.

Overall, it was a great show and I recommend it but if you are struggling mentally some of the messages are a bit tough to swallow.
