Annnd im gonna spin this in a positive way(I know) but hey....
On the first page it's totally snowing! So they had a long term relationship...at the end, it's raining and she says it's spring in that distant land(she's supposed to go to) so yeah, my rose-colored-conclusion is that they stay together....
disclaimer - even if its not the case they hadn't realized spring had sprung because they're soooo in love <3
