In my opinion, it's a very strange decision - for more than half of the game your choice practically does not affect anything - but here you have 3 options to choose from, but the choice is almost obvious. It seems to me that in this case, the perfect solution (Elegant solution, 47!
) would be to make an illusion of choice - the protagonist chooses - Korra or Jinora - and the one that he did not choose refuses to leave and in the end everything goes to the harem ending. And all three scenes (Korra, Jinora, both) are available with the ability to repeat. And it seems to me that this is quite consistent with how it was most of the game.
