End of Volume 9, Chapter 63 'Path'. It's at the end of christmas, and she's walking with him back towards his family's cake shop, and it just happens somewhere in the middle of the street. Afterwards, they go their separate ways, since Hori's out there with not enough layers anyway, and Miyamura has to get back to work.@Kirime which chapter is the marriage proposal again?
Yeah, but Christmas isn't the end of the school year. So we're basically getting everything 'incidental' that potentially happens from January to March stretched out over multiple volumes. They don't particularly matter because slice of life and the big moment's already happened, but still. Slice of life set during school generally continues until graduation, I think?@whater your name is, mr. weird hentai code
the "final chapter" is at chp. 63
and yes, when i looking up in my shelves, vol.9 does feels like the final volume. with how everyone spent their christmas and all, and ended up with the marriage proposal. Doesn't mind the eternal fillers though
