As far as I could gather, the chinese are expert in these kinds of plots.They produced a big number of these "fall into a novel" dramas. Koreans have done just a few and I have seen only two I did not particularly like: Extraordinary You and Pop Out Boy. The first one is hugely popular but the only thing I liked about it was the main male cast, a real eye candy who have gone on to forge huge careers for themselves. And I discovered the meaning of second lead syndrome there. Pop Out Boy was a cute little web drama, better than EY.

And then there is this one. The plot revolves around a young idol singer who suddenly finds herself a villain in her favourite webnovel. She unwittingly changes the plot of the novel and becomes a main FL in a love triangle. So as you see nothing new. But here is the turning point: this drama gives a scathing portrayal and expresses a severe criticism of social media and the power that a bunch of frustrated netizens hold in their little hands. And that is refreshing. The young idol singer is used to mean comments about her on SNS and even though she usually just waits for the storm to pass without commenting, it is visibly taking a toll on her. In order to escape it, she disappears into a novel and tries using the SNs for her advantage and it backfires badly making her realize that one needs to fight it and not just let it be and pay no attention to it.

Nana as the idol Yoo Jebi is perfect: innocent asn sincere and smart and realistic who suddenly gets to live her final year of high school anonymous. Gently and sweetly she brings about change in usual high school dynamics (there is "royalty" the F4, the four high school studs!!!And of cours a group of bullying mean girls! And the innocent punching ball! The usual high school cast of characters!)

No character is aware that they are in a novel: nobody thinks it is strange that there is noone on the roads (how did they manage to film so many scenes in public empty places? It does look like a "novel" village setting so maybe it was a soundstage somewhere...), that characters appear and then disappear without without anyone taking notice etc.etc. the usual novel tropes! And of course there is the second lead who almost gave me a SLS but the writers managed to put that threat under control quickly. Yoon Hyun Sook who played the SML was amazing, so sweet and pretty (I'd love to see him in a bl!lol).
This web drama did not have as many eye candy as EY but plotwise it was perfect. They even managed to figure out a credible solution for the main couple.

The resolution of internet troll problem is unfortunately overly optimistic! I personally do not believe in good human nature. People are not like that: everything most of us do is guided by the seven deadly sins and the internet is letting us get away with things that the good upbringing and education managed to curtail and limit before. Now it is feast for all, in blessed anonymity!

The story is really sweet, the actors are good, the writing logical,the world building credible and production value high.
