The only reason it doesn't get a higher rating is I feel the ending is a bit too abrupt as it literally just ends which sort of threw me off. But if you can look past that it really is worth watching.
In comparison it's Korean equivalent does not match up at all! If you were to pick one I'd say start with this version first.
A big downside was the length sadly it only has 13 episodes of 30 minutes each and because of that the ending seemed a little rushed.
