my feelings on this ending were super mixed at first but after thinking about it more i definitely like it a lot. i think it's probably the first manga i've read that has aro/ace characters but still follows the model of a typical romance and has the characters end up together at the end.
the ending initially felt really unsatisfying but i've realized that i probably just feel that way because the type of feelings the main pair have for eachother aren't ones that i personally relate to and don't match what i myself would want in a relationship. thinking about it further though, the ending absolutely aligns with the core message of the story, that you don't need a traditionally romantic or sexual relationship to be happy or fulfilled. the build up felt natural too, it wasn't a bait-and-switch gal pals ending or anything like that, by the final volume (and honestly way earlier than that) it was very clear what direction the story was going in and it never tries to mislead the reader, it's always very upfront about the fact that the main duo are in love but not sexually attracted to eachother. so it was kinda my fault for applying my normal expectations towards the ending and it made me realize how pessimistic i actually am in regards to non-romantic endings in gay stories lol
apart from that i just really enjoyed the emphasis the story places on the comfort found in other people, i love the whole bit with hinako and asahi telling eachother "you're always welcome to run away here" because while they're talking about their actual physical homes literally speaking, the implied meaning there is obv that they themselves can always provide a feeling of home for eachother given the comfort they feel in eachother's presence. which is just a really sweet message and one that resonated with me a lot.
overall very unique series, asexual characters in romance manga are a rare thing so it was really cool to experience a story with such a heavy focus on the characters coming to terms with that and with being in love despite lacking the physical attraction that usually defines a relationship. it felt nice to have a semi-platonic ending that was actually for the sake of representation and made total sense for the story rather than the stereotypical shoehorned gal pals ending.
