Did You Know?


The scriptwriter is inspired by the Incheon Elementary School Murder case in 2017. In 2017, at the Incheon Elementary School murder trial, when the victim's mother asked the defendant what was the hardest thing right now, the defendant's answer was not sorry or guilt. Instead, the defendant said, "The weather is nice, but it's the hardest for me not to see cherry blossoms." The whole nation was shocked and furious at the defendant's response. See more »

User Reviews

No Korean series is as great as the Mouse series.
23 April 2021 | by parighghSee all my reviews

Many serials do not pay attention to the elements. They do not use symbols. The actor is not chosen behind the scenes in a way that shows the actor's feelings, and as a result, these films are lame in terms of staging. But this is not the case in the series Mouse. And all these issues have been addressed. Many of the serials are such that they do not need any analysis, but you had to analyze the serial "Mouse" in order to understand what the director intends to do with this scenario! The story maintains its coherence and it is clear why it is moving forward. There was an irrational issue that we realized in the two new episodes was not such a thing and it went quite logically. This series challenged us. I've just listed things here that many of the series I call great do not have these features.
