Bride of the Water God

A lot of people compared this drama to Goblin but the ending of this drama is way better than that of Goblin. I actually like the story of this drama. There's probably some missing factor to get hooked with it but a least in this drama everything make sense... Well except for that swimming part with awkward hands though... :D 
There's a lot of things shown in every episode of this drama... How much will you give up for power (Ha Baek)... for friendship (Bireom)... for family (Soah's dad)... for humanity (Mr Shin)... for love (Moorah and Ha Baek).... and for yourself (Mr Shin and Ha Baek)... 
Life is all about your journey and how strong enough are you to journey further. I also commend Mr Shin's assistant for trying to make that friendnemy of SoAh realize her actions to be a better person. Her attitude is really annoying. I also like how it ended... fair enough for a human and deity love story.
This drama is based on the 2006 sunjung manhwa Bride of the Water God by Yoon Mi-kyung.

When the god of the Land of Water, Lord Ha-baek (Nam Joo-hyuk) visits earth to retrieve the sacred stones needed for him to claim the throne of the Divine Realm, he seeks out the help of neuropsychiatrist So-ah (Shin Se-Kyung), the only remaining descendant from a middle-class family fated to serve him for generations. Because she doesn't believe he's a god and mistakes him for suffering from a mental illness, she initially resists him. However, after she meets the god of the Land of the Sky, Bi-ryeom, (Gong Myung), the goddess of the Land of Water, Mu-ra (Krystal), and the demigod Hu-ye (Lim Ju-hwan), she decides to aid him in his quest. - Wiki
