What if one juror says not guilty?

If one juror says "not guilty," it can lead to a hung jury, meaning the jurors are unable to reach a unanimous decision. In many jurisdictions, a not guilty verdict from even a single juror prevents a conviction. The case may then be retried with a new jury, or the prosecution may choose to dismiss the charges altogether. The presence of a dissenting juror highlights the importance of reasonable doubt in the legal process.
