That's not a conclusion. It's a middle finger. At least it looks like one. Some NGE shit, but not as confusing.
I get, that he let go of her, which means fin. The death sneaks disappeared, so it's hinted they gonna win. But the chapters before also throw those kind of things out of the window over and over again. So it might have been the last chapter, because the MC might have walked directly into his doom as far as we know.
God, I'm going to miss this manga. That was quite some quality. I hoped MC would get together with the ex-idol. She was the best match up for him after FMC. Or that ghostgirl would posses ghost's body or something.
9/10 (Badly executed ending not part of the final rating out of respect.)
