In stories about romance, the resolution is almost always some form of “yes”. A tie being forged, a life altered. It’s striking to see a story where the ultimate resolution is — and always had to be — “No, never, not with anyone.” Instead of going from absence to presence, the arc is in acknowledging and embracing the absence as what was right for her all along. Not an arc of change, but of accepting that it won’t happen.
It’s not an easy story to tell. You’ll never read a WSJ manga about someone who’s always been pressured to become the Ninja Wizard Champion deciding that he doesn’t want to and doesn’t have to. I don’t think popular storytelling will ever lend itself to that kind of narrative. But there’s a place for it. I’m glad stories like this are being told.
EDIT: Another thought. Jump tells stories about adolescence, which are fundamentally stories about becoming. And this is a story about staying, and accepting that the place you’ve been in for a long time was always the right place. It’s the kind of narrative that arguably only really works with an adult protagonist.
