Mono would be exactly that, why else wouldn't you want to share or be open? Because you want to possess, because you are jealous, which is exactly what Halsin is not and of course he is poly, he doesn't have to show it exactly in the game, he says it and he is open to everyone.
Again. Is there anything wrong of adding an option to tell him something like that: "I love you and I want to be with you, but I am mono, I don't like to share or be shared" and have him(or rather writers) to respond to this. Would be good testament.
