The story at the beginning closely follows the webtoon and the only reason why it knocks off some stars is because i personally am not a fan of romance being a plotline especially as it's not the theme in the webtoon however it later focuses more on the mystery of the other body.
I don't want to give too much away but if you read the webtoon it is not a bad binge watching drama for quarantine. For the webtoon fans who love jay + daniel moments it's a win for you because jay can speak and gets a more prominent character at a point into the drama
Solomon's acting is impeccable and you will not be disappointed. I'm sorry but that boy is amazing I can't even do him justice with words on how diverse and how amazing his acting is in this drama it's a must watch for park solomon fans too.
