I think it's pretty clear cut that the two of them will remain in this wholesome relationship until the end. That said, I also find the dragon loli's mini character arc a little wack. She was just introduced (and thus flimsy as a character, since we know nothing about her motivations YET), asks for a fight, loses, then proclaims that "only victory matters" after a pretty cocky display. They're evidently hinting at there being some sort of sad backstory to her, but I feel like the way it was executed makes HER look like a bad person; which might be what they're going for, but I'm not a fan since it detracts from the main focus of introducing her and the sop backstory.
