Well gee, the story was quite explicit...........and it seems we are still in a flashback zone, also the fact that she still hadn't done it with the suppose fiancé (unless she was lying) means that they weren't very "tight", wonder if is one of those cases where the Hero promised to marry her and disappeared to go and fight the Demon King.
Thanks for the chapter, I still wonder when are we going to find out what is the overall role of our protagonist in our story, I guess chapter 3 will finally connect to the flashback (flash forward?).
