That was not a K1 visa application - it was a petition. You should familiarize yourself with the process and the terms, they matter.
They probably won't outright reject your petition, but you may get delayed with RFE(s), because the two main requirements are evidence of meeting in the two years prior, and evidence of intent to marry. If you simply described your circumstances of meeting in #54 without supporting evidence, they will RFE that.
