I see, what's going to happen:
She gets a job in the capital (happened this chapter). Now I guess the story will make a timeskip very soon and she creates a small harem. At some point the hero will also visit the capital again. He'll be swooned by all kind of girls (again) and again he will have forgotten about his GF. But this time around he will encounter her and see, that SHE GOT A LIFE WITHOUT HIM? This will trigger him and drama ensures, as he is the hero and his needs have to be satisfied and she should yield "For the Empire!" and why did she turn up, that little whore (That what the other girls will say.).
We also don't know the full background story to that:
Have the last reincarnated heros all been the same guy (soul) that has been reincarnated (without memories of course)? Or is it a new douche bag all the time?
Have those hero been arseholes to begin with or have they been forced/manipulated into abandoning her?
If this time around hero is an arse, the BGS-configureiation (BackGroundStory) doesn't matter. Kill him with fire. But judging from how the best friend of hers reacted on "I won't be waiting", I fear the hero is actually a nice guy. How it might go depends on the BGS in this case.
- If it's the same guy in all lives and he wasn't forced to leave her (I mean really forced! Not like "You have to marry the princess or the kingdom will fall into chaos.", that's the kings shit to undo. In this case he left on his own decision.), crash'n'burn no matter how sweet he is this time around.
- In case the past heros have been somehow forced, it's a different story. The hero might turn out to be, well, the hero of this story.
The sad part is...I believe she couldn't turn him down as a "childhood friend turning lover" either. Either she couldn't tell, if he would become the hero (even if she had a good hunch) and didn't want to shoot him down, because of that (Husband-get this time around! Please don't forget, she isn't from Earth, but just cold as ice, as she is a burned child) or ... Just imagine there is the hero and he has to save mankind in the near future or ... a lot of people die or it's even THE END! Would you break that guys heart and maybe even his fighting spirit by turning him down? Sure, it would be the right thing to do, but....>>>THE END<<< is right around the corner!
Welp. I'm majorly interested in the next few chapters until scumb...the hero will turn up. I want to know, how things really are.
Edit: Oh yeah, there is also the matter, if she actually is a terrible wife. On the past heros: They all promised to come back, so I believe they had a good time with her. That cheating husband from life 2 can go and suck it! But that guy from life 3 might have left her for a good reason. Maybe she was cold that time around and married because of convenience. I wouldn't blame her too much since, 1. Waited|grew old|died from shock (after a year) 2. Also waited, but got the message earlier|married a scumbag|was bullied and 3. Waited, but also got left. Maybe she swooned a poor, nice fellow. Not a nice thing to do, but ... yeah... Or that guy just was a scumbag, too.
