I admit I do get bored sometimes while watching it but what I do i watch 2-3 episodes drop it for a couple of days and return back watching. I think the chemo between Kim Sung Yeo and Jo Yang Sun is great. Yes Kim Sung Yeo is a bit clumsy, naive, stubborn but she loves Jo Yang Sun and that's what makes her character unique. I do like her here a lot. In this drama she almost looks like young girl more like an adolescent, her mimics is also quite well. Like even if you do not watch it with subs, you can understand she's shocked, unhappy, surprises. LJG can't say anything negative to his acting and he is very handsome, he speaks with his eyes. GWi Lee Soo Hyuk for me he's a perfect match for a Vampire, he is a perfect with for supernatural characters. He has a pretty unique face comparing LJG, Baekhyun, Changmin, Kang Ha Neul, Bo Gum, Lee Min Ho etc Yes Yang Sun's ex lover as her reincarnated self gonna play an important role in the drama but I do not really ship them here. Didn't really like the music but whoever is their stylist is s/he done a great job. I loved the outfits. Actually when YS first saw Choi Hye Ryung as her reincarnated self Lee Myung Hee the outfit she was wearing reminded me what Hae Soo was wearing in Scarlet Heart Ryeo in one of the episodes. The drama could be less boring but more attractive - exciting to us as audience.
