Noob question: the wedding [KCD2]

Ok so I finished the blacksmith’s quests and can go to the wedding with. I also finished all of the miller’s quests up till the final of getting the perfume and dress and girl and all. Can I finish those remaining quests for him and still get to choose who to go with or does it lock me in? I don’t really care which one I go with but just don’t want to mess anything up. Searched around and didn’t find I think any clear answers. I think I finished all of the first map quests and side quests minus stealing the musical instrument from the carpenter’s house which I might still do

Thanks
