The end actually had a pretty nice and happy subtext to it for me. She puts Nami puts a Bandage on Juri's neck and tells her to absolutely not take it off while they're together. And on the last page it says "..that will last as long as Nami's bandages.", which essentially means they'll be together as long as Juri keeps Nami's bandage on, which is up to her, according to Nami.
Aka happy end, at least that's how i choose to see it.
