Extraordinary You was the first drama ever I watched that dealt with the webtoon characters! It was also the drama where I discovered the concept of Second Lead Syndrome! And I hated it!
Well, this is another drama dealing with webtoon characters and which has a SLS but it is shorter, cuter and better!

A high school girl makes a wish on her birthday but it does not really turn out to be what she wanted. A character from her mother's webtoon comes to life and keeps saying the most cringiest things ever! In spite of that, she falls for him. There is also her best friend who's been in love for her but never said anything (SLS unfortunately!).

The plot is nothing new or original, very predictable and with a few plotholes but since it is fantasy.... The drama features only kids and there are no adults involved in the story! I can understand this in a webtoon but this is a web drama and an adult presence could make this more believable: the girl's mother, the artist who created the webtoon, is dead so she lives alone. Apparently she does not have any relatives (father, grandparents, cousins?). Well it is fantasy!
Her mother used her name to create the female character in the comic and since it became hugely popular, she had to suffer everyone making a reference to the comic when they met for the first time. And therefore she hated the comic and the cringy character with her name her mother created.
I could so relate to this. When I was a kid, there was this hugely popular pop song with my name in the title so every time I'd meet someone, they would sing this song to me. I ended up hating my own name! And I still do!
The love triangle has been dealt with in the usual manner and for once I am glad that there was no apology for not returning feelings and they managed to stay friends.
This webdrama is quite funny as well! There is a side character, a redhaired girl who becomes a harpy(your typical high school top of the foodchain pretty girl) every time she sees the ML with someone but as soon as he moves out of the way, she realizes she'd done something stupid and apologizes. An original comic relief character!
And that's it for the story: just a romance triangle with a happy ending! I wish they explained it more but since it is fantasy, logical explanations are not needed.

The actors were all good and I hope to see more of them in the future. This is a nice short watch, no cringe or angst so it is very relaxing!
