Kazuma and his many "Love" Interests

So, I binged all of Konosuba (minus the Megumin backstory because I wanted to get straight to S3) and I was wondering something:

Who does Kazuma end up with, if any at all? There's a whole bunch of misinformation and the main consensus is that he ends up with Megumin. Is this true?

I personally think that the lying is funny but I would like a solid answer. I noticed that there seemed to be some kind of romance between him and Megumin and also possibly Darkness, but the manga site I use isn't properly updated so I can't read ahead.

If anyone could shine some light on this, this would be greatly appreciated. 🙏
