I have to be honest, I couldn't get very far into this drama with the age gap. Of course the Goblin is a nearly 1000 year old supernatural being, however there is a difference between this and other supernatural romances with age gaps that make it less acceptable. Firstly, the female lead starts out as *underage*. The actual actors have a 12 year gap and the man looks like he could be her father which makes it much more awkward in the show seeing the male lead essentially watch the female lead as she grows up. I felt so uncomfortable in every scene where she's a highschooler, a literal child, with a grown man the show is hinting at romance with. Regardless if they don't doing anything before she is older, it's strange to wait until it's legal and to even hint at feelings when she is so obviously a child. Unfortunately the interesting main storyline couldn't distract me enough to ignore and enjoy this drama. Yikes.
