Honesty saying please do not watch the 10th episode.....the drama is very good till 9th ep but 10th ep ruined everything....I am regretting watching the last ep....there couldn't be any worse ending than this.....
If you wanna watch 10th episode watch it on your own risk...

After reading few comments I realized the webtoon version is Good...so it's better to read the webtoon instead of watching the 2nd season.

After watching first season I was eagerly waiting for the 2nd season and was curious about what will happen... if there will be a happy ending? or who will survive? etc.....But Now I regret watching 2nd season
