It tried to be artsy and unique. It also tried to have some kind of message.

It succeeded at the former, and failed at the latter as most people including myself have no idea what the drama wanted to say, and all the "interpretations" I read so far feel like a stretch or projection. Since it was adapted from webtoon chances are the author was just making shit up as they went.

Each episode tells a different a story focused on different character. This, combined with constant time skips makes it hard to get attached to anyone and doesn't really motivate to watch the next episodes.

Some observations:
-Iphones were only invented in 2007, android smartphones in 2008. I find it unlikely that people in 2008 would own modern style smartphones.
-Also, these kinda streamers/youtubers/influencers who get money for dancing live on streaming sites in real time and would chat with their audience or whatever wasn't a thing until 2010's. Was 2008 so long ago that people no longer remember was 2008 was actually like?
-Recovery after plastic surgery doesn't take so fast, and the timeline of her pregnancy is very sus too.
-Police and special forces not shooting as soon as armed person pointed a gun, instead giving warnings until she shot is not how police works. It's laughable.
-Unconscious person wakening up underwater, not drowning and shooting her gun there? likely story
-Shotguns have quite a lot of penetration so shielding another person with your own body gets you both killed

Other then all this nonesense, the acting was great (especially from Yeom Hyeran, what a talented actress) and occasional black comedy parts were genuinely funny. The cinematography and camerawork were amazing too.
