I'm liking this drama so far cause of three of the main leads. Lee Dong Wook, Kim Sun Ah, and the doctor. All three are doing an amazing job at playing interesting characters with lots of layers.
And this drama does really well at adding little scenes throughout that are so funny/amusing/cute/touching that they feel like eating a piece of fudge. For example, when Yeon Jae's (KSA) mom comes back home after their argument she coldly asks her daughter how she could still eat before slamming the door to her room. Or at the club when Ji Wook (LDW) was called out by the other female lead and the singer/host boy walks in and Ji Wook just bites on the ice cube. It fit his character perfectly. Also when Yeon Jae visited her father's grave and at first got angry and yelled at him vowing never to come back. Then comes back a little while later with Soju and apologizes for being harsh, cause she's just scared and has no one to lean on. I found that scene especially touching and quite funny. And the directing of the scene when Ji Wook leaves the club and is in his car, that was beautifully done imo.
It was these little scenes, rather than the overall plot, that made me enjoy the first couple of episodes of the show. I hope they keep up this pace and style.
