This manhwa is the best art-wise I've ever read. I love this style - detailed, with a lot of heart put into clothes, enviroment. Therefore: 10 for the art.

Story: 7
At the beginning I though it was heading for some master-servant plotstyle, which can be enjoyed, of course, to some extent. But it did not.
There are moments, when the plot goes a little bit too fast to really enjoy it, but there are really great moment, like Yuri revealing her family's secret, and Boris' actions at the end.

The story had a lot of comical situation, that can be enjoyed. There were really WEIRD situations, but it was also combined with a lot of humour.
Maybe because of the humorous side, it lacked the feel of developing romantic feelings...

What I didn't enjoy were the absurd character od Maxima (?). This volume that revolved around her was really annoying. I thought it was thrown in to make a huge impact on the story, but in the end it was cut off maybe because of the authors change of heart?

Overall, even though this manhwa had really great and really bad moments, I recommend it to get a fresh view on manhwa, that - for a change- is not centered on a high-school romance between a bad boy and good girl ;) (had too much of it lately)
The whole ending arc was totally the best part of the whole manhwa!! It made me happy to see the main chara evolve to that point :) and of course, THE ART was amazing (again)!
