I think part of the mess is bc few of us actually know Japanese. Perhaps he/she has explained the timeline thoroughly on her pixiv page, and we just don't know that yet cuz again, we don't know Japanese
Hate to tell you guys this but the raw pixiv content ends at chapter 12 and hasn't been updated since last year's december. so either the manga is published or well have to end with a cliffhanger
