I personally LOVE park min young... She's the reason why I'm watching this kdrama to the end in the first place. Casting is the only thing justified in this drama. Everything else is.... meh.
FL and ML shines throughout the episodes. One thing I loved in this is that communication between the people are not dramatic. Everyone speaks their mind to the other person. The method of conveying the thoughts of characters are straight forward, thus decreasing the unnecessary dramatic scenes. It is waay too rare to see in kdramas.
ML/FL, second leads and even supporting actors are way too good for the characters given.
Production quality is ?. That is not at all compromised here.
Story, OST, script, director, editing are all only mid.
