Yes, alternatively, you may be right. Elsa's role and her sexual as well as all other inclinations are, at this point, certainly anything but clear which continues to make the story so very intriguing. It will be fascinating to hopefully find out at some point how impactful her character will end up being and what, if any, interest she has in the mc, either in terms of his potential prowess or in an emotional way or indeed both.
I wonder too if there may be a twist in the tale (pun) with regard to Alice's involvement and intent with regard to the mc and/or Elsa. It would be ironic if the mc unseats the woman who stole his idea and achieves rightful recognition and promotion only for Alice to go off with Elsa leaving him either with the girl next door or, more likely I suspect, completely alone again.
As I said, it's all very intriguing.
