It's been completed for a while now! The final chapter was published in Japan back in 2021, so you can read the whole story without waiting. I remember feeling a bit bittersweet when it ended, but the conclusion wraps up the main romance nicely. Definitely a satisfying binge read if you're into that classic shoujo drama.
Would an anime even do it justice? The watercolor-esque flashback scenes are a huge part of the mood. If a studio like Kyoto Animation picked it up, maybe. But if it gets handed to some overworked studio churning out generic seasonal romance, it'll just flatten everything that makes the manga special. The charm is in the details, and anime adaptations often sand those details right off.
Is there an anime adaptation? Sometimes watching the anime first gives you the broad strokes of the main plot, then you can dive into the manga and read everything in any order because you already know the key beats. It's a different strategy, but it works for some.
