'Zenzen Daijoubu' is Actually Correct

The phrase 'Zenzen Daijoubu' (which translates to 'Totally Fine' or 'Completely Okay'), which some people find awkward, has historically been used with 'Zenzen' + a positive form for a very long time. There's no evidence to suggest it started being used incorrectly after the 'Zenzen' + negative form became standard. Originally, 'Zenzen' + positive form was commonly used, but at some point, a misconception arose that 'Zenzen' should only be used with negative forms. So, feel free to use it without worrying; it's totally fine.
