I read the reviews which were generally very positive. The rating of (8 and up) for this drama made me consider it and so, I embarked on it with eagerness.

The first episode was "meh". I did not really like the vibes and all. Nevertheless, I thought I should give it a chance and so, I watched the second episode. The second episode made me shake my head and cluck my tongue in both disgust and annoyance.

What I didn't like:
-The blatant unfairness shown towards the smart students versus the less-intelligent students.
-The teachers were extra nice to the smart ones and incorrigibly unreasonable to the less-able students. 1st example: Teacher allowed smart student to use his phone while a less-intelligent student was being disparaged for wanting to use the washroom. 2nd example: Principal berated the less-intelligent student severely and punished the less-intelligent student by making her write a 5000-word reflection while the smart student was gently admonished and advised to write a 500-word reflection.
-I didn't like the double standards displayed. Weren't teachers and principals supposed to be fair and reasonable?
-The male lead was annoying. He kept rushing about here and there without explanation.
-The female lead wasn't cute. She was also annoying in her bumbling manner.

Despite the very positive reviews from the other viewers, I have decided that I have to drop this drama for the sake of my well-being. I do not wish to be stressed out and irked by a drama which does not resonate with me.

Overall: Don't know why others say it is good. Personally, I find it very lame!!
