I'm not surprised of the medium-low rating because this drama is not for everyone. It's odd, a little twisted and leaves many things unsaid until the end. It's a drama that asks you to think and use your brain, to come up with explanations by connecting the dots instead of just giving you all the answers from the start.

That's not to say the story doesn't give answerS. In the end, more or less everything is explained. The story starts in the middle and lets you get accustomed to all the weirdness and the characters before it starts to give you explanations.

Overall, it's a fun, endearing and sometimes tearinducing watch. I enjoyed it very much even though it's a genre on its own that it's even hard to explain with words. Definitely a pleasant watch I would recommend to everyone who's looking for something spooky but not scary, and to everyone who wants to have a good laugh.

//SPOILERS AHEAD//

I gave 8.5 because the ending could probably benefit of a couple more minutes to see where the other characters, especially the professor, ended up. They also teased romance for the whole duration of the series, but it seems that in the end either they leave the ending to your imagination, or it was put aside completely (I'm more for the first option, since there is /that/ scene towards the very end between the two leads, so I can't believe they just didn't pursue a relationship after that.)
