I didn't get super far into it before I dropped this. (I am very picky tho, and drop a lot of things quickly, so take that as you will.)

Here are some of my observations along the way.

Pro:
- I really liked Moon Gayoung and Joy in this.
- I liked how much of a b*tch Suji was, but not only in a bad way. She stood up for her friends and for classmates. There was an altruism to he bitchiness. I liked it.
- I love the source material. I'm a big fan of Dangerous Liasons (the book) and I'm always happy to see new adaptations of it.

Con:
- After the fifth rich kid main character had a fight with their parents I thought it really was a bit much. Not a single one of them has a decent parent? Come on... Also, the reasons for which Suji hates her mother are unclear to me (maybe they're gonna be explained later on, but since for the others reasons were given immediately, I wasn't betting on it.)
- What happened between Suji and the art teacher was not quite clear to me. I seemed like he reciprocated her feelings (yikes) but then was found out and fired? That's how that scene read to me. But in that case I don't understand why Suji held a grudge against him for four years to the point where she wanted to humiliate him at the graduation ceremony...
- Taehee's fight with her mother was unrealistic to me. She seemed like a nice girl, so for her to confront her mother and kick her out of her life when she was clearly trying to make amends because her mother didn't much call when Taehee and her dad lived in Europe? It just felt psychologically unrealistic to me since Taehee wasn't otherwise shown as confrontational and also, that's just not how most children behave towards distant (but obviously well-meaning) parents. It felt like drama for the sake of drama.
- The mother who's a model seemed to have extremely low self-esteem for what she is. She looked really good, I didn't have a problem believing she was actually a model bc of that but instead to me the problem was her body language. She was slouching all the time, she cried in public, she was a doormat when others talked down to her. I just felt a supermodel (who's prob been in the industry for over 20 years at that point) would know better. But instead she was standing in front of a 20 year old, twiddling her thumbs, looking down at her own feet, slouching, while whining to him how her daughter doesn't love her. Just very weird acting choice. Or maybe directorial vision? I don't know.
- Speaking of the model mama: All the age gap relationships (and non-relationships) made me a little uncomfy. Especially since so far into the story nobody even acknowledged that they're weird.

Neutral:
- It felt kinda steamy for a kdrama, which in turn made it feel kinda like an american show like gossip girl or riverdale (hence the comparison in the title). I don't think this is neither good nor bad so I gave it it's own category :)

Overall I did enjoy this show, but the drama felt too unrealistic and forced for me to continue. Would love to see Suji take revenge on even more people tho, so who knows, I might actually pick it up again at some point.

And that's my two cents!
