You'll be just fine, no deny for sure. If you can show them strong evidence that your relationship is real and not for Green Card fraud.
I have seen so many people posted in here that they worried about their K1 process because they only met once before they filed I-129F.
And people also replied to them negatively that they will for sure get deny. But no, most of them got the visa just fine and now in the US.
Once of the post they only met each other for 6 days then file for I-129F and never meet again until they got the visa.
So you don't have to be worry, in USCIS I-129F intructions also stated it clear that you need to meet at least once within 2 years of filing.
You are fine.
