"I've seen it thousand times"..
The beginning is promising, I thought "This might be the best one this year actually"..
Around 8th or 9th episode you notice how they lack ideas and innovation, as if they took 100 other dramas and took parts of it and tried to adapt it to this series. It doesn't go well together, 99% of characters are over 30, they all act if they have an teenage alter ego. It doesn't fit when it comes to serious scenes because you can't take them seriously. They threw scenes one after another, but gradually deepen the plot and having a rich ending was not an option. As if they didn't have ideas or material for continuing the original idea (the first few episodes). The drama is alright, but it reminded me a lot of many (seriously, many) things that I've seen already. I'm used to typical k-drama acting and some repetitive scenes, but this was too much.
The acting was fairly good in general.
Since it's a series I can't really comment on how realistic some situations and facts are, they could have been made more accurate, but it was okay without getting too much into facts.
For me personally, I've seen better.
