Korean Drama "User Not Found" is a korean web drama with an interesting plot about two girls with the same name, changing identities.

The drama starts off strong, with the introduction of the characters and the slow build up of the friendship between the girls. The story progresses smoothly, with few twists and intrigues, focusing rather on the characters, their feelings and their actions. However, the drama started getting boring and more hectic towards the ending. The conclusion was rushed, and it was anticlimactic and pretty much a letdown. And, in the end, the main character proved to be a boring one, with no personality and just those tiring damsel in distress vibes. The romance was cute, on the other hand, but did not mature nicely.

So, overall, 4 out of 10.
