There is a sequence. The author didn't want that the fight to be easy. But because a lot of people ask for help now you can buy drinks on the bar to help with the fight.
I will not give you the sequence but a fine hint is that you want choose the options that look the less aggressive ones. The first and second paragraph changes and can give you a heads-up if you on the right path. I think is a good idea to save right before the fight and read the lines with attention <3
