After "struggling" for more than half of the drama and saw how the story goes, I don't think they could wrapped up this drama prettily. Tbh, I still watch it simply because I want to know how they will end this mess... We have main leads, but somehow the main story itself doesn't belong to them. We have a promising villain character, but he barely got enough screen time. We have several interesting side characters, but their arcs were left hanging in the air. And how can I forget, we have so many questions after each episode aired but, alas, just few answers popped up on next episode.
At this point, it wouldn't be surprising if on the last scene there's LG, riding Maximus towards another gate/door (that's my imagination LOL)
