When starting a new drama I usually go in expecting nothing because the drama ends up being more impressive without expectations and gives me a lot to drool over. But this drama gave me nothing. The twists were expected, the storyline was boring and the characters were less than likable, a big problem because there are so many. It tries to do way more than what it has time for. Just barely exploring the plot points it brings up. Details are just flat out told to viewers via character dialogue/flashbacks (there are so many flashbacks). I wanna see some action not storylines handfed to me. I don't know who the director is but I would avoid future dramas shot by this person seeing how bad and bland the shots were. At times the camera cuts to this first person shaky frame which is so unflattering.

As for acting, I think everybody did their best with what was given to them. Though, I did find Kang Sol A's acting way over the top. No show stealers here though. There's a lot of screaming (thank you old office man who has zero significance to the plot), this show seems to think loud equals funny or emotional. You're not delivering anything, just hurting my ears. I can't handle the morally righteousness of the main characters. The one character that strays from that; Sungjae is given the bare minimum. There being so many characters is the downfall of this show. You can't establish an emotional connection with them because of the lack of deep diving characters are supposed to be given. So at the end I don't care about who gets to be happy, I just want the show to be over.

As for music, there are only 3 songs here. It gets really old really fast. It's annoying that the songs come on and basically tell you hey this scene is supposed to be emotional, hey this scene is supposed to be suspenseful, and oh hey look the characters are studying. It's annoying when the emotional music comes on and you're not even moved by the scene. You're stuck there cringing because what the characters said wasn't deep at all and here plays th-We are We are Where are we? We are We are.

With all that said, I don't like this drama, I feel like I wasted my time and was blinded by an all star cast. I would still recommend you watch it, it might be your cup of lukewarm tea. But there are way better dramas out there, enjoy watching.
