Dear @Michaelson27,
Welcome back to the Wefugees Community and thank you for reaching out to us.
I remember that you asked a very similar question a few weeks ago. I hope you have seen my answer on that one?
As far as I know, regulations have not changed since then. In sum, if you plan to stay/live in Germany after the marriage, you might face problems to receive the residence permit if you did not come on a marriage but on a Schengen/tourist visa.
Please get back to us if you have any further questions on this.
All the best,
Meike
