For some reason I really wanted to watch this show, like it was on my watchlist for the longest time. The show started off very interesting, and I really liked the plot. Yes, it is a little bit like Goblin, but this is still a good show that is unique. I really really thought this show had a stellar OST, not only were the singers all big names, but the songs were also very good. I will start out with my critiques, the reason why I gave this an 8.5 was because this show was very enjoyable, but it was not "next level." It really tried to be and succeeded in some ways, but it was a little predictable and was not some of the other next level kdramas that I have seen. What I did like was that it was a little thought provoking. It really made the audience wonder: what would I do if I had 100 days to live? In general, this show let you put yourself in the shoes of Dong-Kyung, and it made us wonder what we would do given her situation. With the character of Doom, he was not the most likeable male protagonist, and certain traits were overdone, but it did not compromise the show. I was expecting to see him show off his godly powers more, but he was more human than expected. I think that while Park Bo-Young did do an amazing job, the love triangle between the secondary characters did it for me. That was surprisingly interesting, and that kept me gripped and happy to watch it. The main love story was good, but the love triangle was really fun for some reason. Overall this show was good, it was more than simple, but not quite complex and mind blowing. I would recommend it to watch, and it is not hard to watch since episode lengths hardly exceed an hour for the most part. The love triangle and the role and character of the little girl deity was really cool to watch, so I would say give this show a try.
