"If you don't drink, you will be full" wine: There is a scene where Ken drank four bottles of wine in the bar within 20 minutes, and the bartender opened a new bottle. At that time, the bottle of wine I saw was not completely full. When the camera was changed from a different angle, I could see that the bottle became full.
A small mistake that is difficult to discern: The name of the hotel where Ken and Lei often stay is "De Rozenkransje-Brugge", where "Brugge" is the Flemish language of the small city of Bruges. In fact, the name of this hotel made a grammatical error, and the article was not used. "Rozenkrans" means rose garden. Originally, the article "de" should be added in front, but "Rozenkransje" here is a small name. The article "Het" should be added. But then again, even for people who are very proficient in Flemish or German, if they are not their native language, this is usually a very difficult error to find.
