I honestly think it was a very fun show to watch. The Sehun + brother scenes were my favorite part. The amulet subplot was a bit meh but I understand how it fits in the story. I like how the characters were connected from childhood and how we don't have a perfect happy ending. But I feel that the love triangle was not done well. We just have D.O being heartbroken in the end without anybody knowing, well, except Baekhyun ( who didn't have much to do on the show). That monologue about being alone and only being her friend was not a good closing point for D.O's character.
