1. The female lead character is an extremely childish and annoying, haaaardly a mature man can be attracted by her!
2. The plot could be OK if she (FL) would not be so pushy toward the Goblin. God girl, you have to be "hard to get"!!!
3. She just all of the sudden declare herself as a Goblin bride. Self-respect is missing.
4. The good thing about this is Sunny and Grim reaper relationship and probably just because of the actors who work together perfectly.
The conclusion is OVERRATED.
