Guild Wars 2

I just exit during the story (Kiel and Fotm staffs) due to my guild mate ask me to get out from fotm so that i can join his party. And after that, i don’t know how to replay that story again. This EXCLUDE video that explains reason why she needs a volunteer.
Please help me! :’(

I played the story with my guild and the next day took my boyfriend in. As long as the person who hasn’t done story mode starts the fractal you should be able to replay story
