Loved everything from the story to the acting to CGI.

Jang Uk is witty, smart, genius, carefree, jolly minded, lazy, lout, fickle. He isn't a great mage & lacking in power for some reason. Throughout, we'll see his growth. I liked that they didn't show him as a powerful mage who is unbeatable, which is why we can see development.

Mu-Doek is a mysterious person. She is straightforward, isn't afraid of anyone, brave, an expert at lies. I liked how her voice changed into a somewhat mocking tone, but in front of Jang Uk it's different. She has another name, which is Filthy Mu Deok.

Jang Uk & Mu-Doek have a master & maid relationship and also a master & student relationship. In the end, lovers. They focus more on the master-maid & master-student relationship. But there is love between them & it's shown by their actions. They do end up together in the end, but.....

Park Dang Gu is fun-loving, kind, speaks without thinking. Seo Yul is a serious guy who always stands for the right.

Love how Jang UK keeps on teasing Mu-Doek by giving her lots of work.

Loved how unbothered Jang Uk was after breaking Jin family heirloom. Park Jin fell down on the floor while chasing him because of it.

Laughed when Jang Uk asked Maidservant Kim to carry Mu Deok on her back & Seo Yul to carry him, their shocked faces after hearing it.

Angry face of Park Jin when Master Heo tells him that he is a lonely person.

The way Park Jin & Maidservant Kim tease each other for having feelings for Jang UK parents. I love them together. They are my favorite couple.

Laughed at how Jang Uk made Park Dang Gu believe that Mu Deok likes Seo Yul.

Laughed my ass off when Jang Uk, Mu Deok, Park Dang Gu, Maidservant Kim offered that they'd drink the filthy water.

It may seem like Park Jin hates Jang Uk actually, he cares & loves him.

Love Park Jin & Maidservant Kim bickering. Loved the way they were stammering to say each other good-looking.

They way Jung Uk & Mu Deok firmly said they’re not married to Master Lee.

Jung Uk horrified face & reaction when he learns that he drank tea which could lower his libido.

Loved how easily & with a straight face Jang Uk said the Heo Yoon Ok that her looks didn’t impress him.

Laughed when Park Dang Gu asked Park Jin if he has any secret child or not & the embarrassed face of Park Jin.

When Jang Uk & Crown Price came to find their loved ones but ended up seeing each other, it was hilarious.

Park Jin acting like a kid to meet Maidservant Kim is so cute.

I laughed so much when Jang Uk & Mu Deok started acting to get punished. The confused faces of Park Jin, Jin Mu, Crown Price & Sang Ho.

Jang Uk scared face when his serect of having 7 exes was revealed in front of Mu Deok.

The face of Jang Uk when Mu Deok said, "she likes him a lot" & kissed him.

Loved everything. No Complain.
