If all you wanted was my personal take on the chapter, then here, happy?
So Luna is having sex with other men to control her desires for the MC?
I don't know why my post that you quoted is suddenly in Español and had the ispoiler tags removed, but
yeah that's the theory. At least keep the spoiler tags in if you edited it to Spanish.
We don't know if she went all the way this time around because absolutely none of it, not counting Naoto's imagination, has been shown. Not that it would matter if the theory proves true.
Do I personally think she had sex in the latest chapter? Dunno, the author actually never showed what happened. She could have went through with it, she also couldn't have and cancelled after the drinks. She could even had went drinking after doing, or not doing the deed. The current
theory based on what's revealed thus far leans on maybe, but since it's not been proven yet, you choose what you think happened, I won't.
Do I personally think the rumours about her being a slut in the past is true? Dunno, the author never revealed the truth yet. It could be just slander, it could have actually happened. At the moment, it is leaning towards "maybe, but she her reasons" if, AND ONLY IF, she went all the way with the guy in the latest chapter.
Do I personally think she is romantically in love with the MC? No,
at least not yet. What has been shown was that she did not want to separate from him (chapter 4 flashback) indicating dependency (she NEEDS to be beside him to truly feel happy), they did get separated once (her disappearing from Naoto 10 years prior), all her current actions in the present is so that they won't get separated again (because she NEEDS to be beside him to truly feel happy, she likely doesn't even know what it means to be romantically attracted to someone).
Do I personally believe her statement that she does not have a lover? Yes, because of her dependency on the MC's mere presence beside her making her feel truly happy like she had in the past, she does not want or even need ANYTHING ELSE, that may include becoming lovers with the MC. She probably doesn't even know what it means to be "romantically in love" with someone because she feels happy enough just by being within the MC's vicinity.
Do I personally believe the two will be together by the end of the story? In one way or another, yes. This is pretty much guaranteed, but the shape on how they will be together in the end remains a mystery for another day.
Do I personally think the author flew too close to Katsura? Story-wise? No, despite all the sus possibilities that could've meant NTR happened, there's always a way out with the possibility that NTR never happened via not showing the readers what actually happened by blocking the view or a timeskip. IRL? Probably, there are reports of people getting mad about the latest chapter in Twitter, not that it matters, I mean it's Twitter, people get mad at everything there.
Do I personally care much for Katsura's future career as an author? For mainstream consumption? No, what her Editors gave the ok for release is very much career-ending, sabotage levels even one could say if they have the evidence for it. For doujin works? No, unless she makes an official "I'm Gonna Fix That Girl version" of her works, she's not going to be a go-to.
Will I pick a side, YES or NO, in the whole "is the manga NTR or NOT?" debate? No, my side is always "only what the author had revealed so far".
Do I personally think the MC and FMC will have sex? Dunno, the author could write it so the two could have sex the next chapter, the last chapter, or not at all. Until the author reveals the truth, remember... Nothing Is True, Everything is Permitted.
