The Lessons Not Learned.

[Shurrikhan]

The more correct term of reference would be "Natsuko-sama".

I want to believe this is trolling, but...

The only thing they appear to get wrong is that "Natsuko" is, indeed, the family name. The Producer's family name is "Naoki".

This is like someone coming along and telling you that Baker, Smith, Gonzalez, Weber, and Chen can only ever be given names, and that Sally, Thomas, and Juan were, in fact, the family names.

It doesn't take much familiarity, with either the name order or common family and given names themselves, to know which is which.
