But Han can't help being monogamous, it's the way he is. He can't be in love with LK & at the same time be cool with LK fucking around.
So there's an on-again off-again primary relationship between Han & LK, and no configuration that is entirely satisfactory to everyone involved.
Han & LK can be:
- together & exclusive (no-one else gets any LK action)
- together & not exclusive (which distresses Han, & thereby distresses LK)
- not together (intolerable for both, cos soulmates)
