Yes, after taking that choice and it treats this as rumour that may or may not be true, while chapter 6 words it much more as basically what happened.
And yes, MC can feel like they worked hard for it, the difference is that I would not take that option while knowing the whole story. (With the whole story in mind the only of the given options I could imagine to take by now is “Especially because I didn’t even want the promotion, the Captain forced it on me.”, except I play a very different kind of MC)
It’s not that this option makes no sense whatsoever it’s that the whole story changes the context of the choice. And I feel it’s not fair to ask it without giving this to us, because again, for me it means basically having to go back to fit the way I play the MC in a way that makes sense for me in such a situation, what in a published game means to basically restart the whole thing.
Maybe I’m just stupid, but for me it didn’t get that clear how the situation of MC’s promotion played out from the first few chapters until it got spelled out. In my mind around that time I had quite a different scenarion and a MC that would never describe their promotion the way MC did it during the talk with the ROs. However I think the whole context explains quite a few things, that in the beginning of the story annoyed me much (the seeming inconsitency between MC’s abilities, their position and self-appraisal for example), but it is just a lie to say that knowing this from the beginning wouldn’t have hugely influenced my roleplaying of the MC. Instead of imagine them as self-confident and competent (at least on the paper) as seemed to fit for their position, I probably would have imagined that as mostly a front to hide the internal screeching they probably started around the time of their promotion and that only intensified around the time they got this case and I would have adapted how I played the MC from the beginning.
See, the problem for me is that I felt like I lack too much of context in the beginning to get into the character in a way that won’t collide with the things preset of the story, because I just didn’t know that it was preset, macking my decision around that time to that topic just a shot in the dark instead of a deliberate decision. And that’s why I think it’s misplaced.
