It was ok. The premise was fun and interesting, but the story was a bit too rushed to make the relationship between them seem believable.

I think they were doing a parody for Goblin at one point. I can't be sure since I only watched a few episodes of that drama a couple of years ago, but there was a scene where the ML asked "How did you summon me?" and the FL was wearing a red scarf, which was very familiar to me. I wish I knew what else they were parody-ing. I bet it would been so much more hilarious .
