That's why I say we shouldn't be too hard on ourselves, when I used to go to tuition and coaching classes my grades were average but when I left all of that and just did school work my grades improved.
A little over-hyped I'd say, if you expect it to be better than Daily Dose of Sunshine or Dr Romantic kind of dramas because of higher rating then it may not meet your expectations but if you don't compare then it's a really good drama.
