It did feel like the story arc wrapped up but like, I thought this was moving into romance territory and that would be the next/last arc. It's been building since early on when she said she would need to "find somebody else to talk about romance with" which implied she had a crush.
But they're wearing rings, on the ring finger at that. But they didn't even really elaborate on why they're wearing rings. I guess they just skipped over everything off-screen and they're together now? Great, yeah, that's uh... why though?
Can you imagine if you got to the end of the Android Saga and they off-screened Cell? That's what these kinds of series feel like.
Edit: Somebody pointed out that the matching rings are from when Yuzu got sick. Yuzu put it on her ring finger not knowing what it meant. So like... are they even together? Idk, looking bleak.
