Possible, but I am not really convinced - at least I do not impute the same determination about this to the dev with the same certainty. If he really wanted the MC to become the Beta, then why is there are path, where the girl did not fuck the captain, but the MC? I myself did not know about the possibility of a scene with the girl and the captain until I read about it here. So my impression is, that the MC becoming the Beta is only one story option, maybe some kind of punishment for making the wrong choices (or maybe a reward for the right choices for those, who like being the Beta), but not an unavoidable fate for this second chapter. But we will see, what the future will bring.
