I loved this drama, such a unique story!

After this drama, whenever it rains I remember Goblin and think to myself: "Oh no, is he sad again? :(" The male lead of course is my crush :D but the female lead is also sooo cute! I loved her bubbly personality and positive energy! Yes, she did act a bit childish as many people said, but I personally didn't mind it because I thought it suited her very well.

In general, it's a very cute drama and one of the best ones I have seen. Although the last few episodes could have been better, in my opinion.

[Downsides]:

1) VERY slow
I had to watch 90% of this drama at x1.5 speed due to its slow pace. Many scenes were also shot in slow motion.

2) Fillers / Repetitive Scenes
I had to skip over A LOT of flashback scenes of past memories. Honestly, they could have made this drama 8 episodes instead of 16.

3) Age Difference
There was a huge age gap between the two leads. It looked as if he was in his 40s, dating a high school student. It was a bit weird, but I had to ignore it and focus on their adorable personalities to enjoy the drama.

Despite all that, I'm glad I watched this drama and I still recommend people to watch it.
Enjoy :)
