Honestly this was entertaining, with how convoluted it was.
Granted it feels kinda like it is a scene of a different manga. And it remains unclear where the author is going with this new characters introduction.
I'm not really sure what the authors goals for the series is though.
Like to use other series as an example: one piece is about adventure, nakama, freedom/creativity. It has basically everything in it, but those attributes are it's core principles throughout everything.
Star wars is a sci-fi space opera that expanded to become a family drama.
Rewriting our Love story, a webtoon about a former couple who go back into their past when they were still dating at college, but body swapped, is about learning more about each other and clearing up the mistakes and misunderstandings, and rekindling the spark. Walking a mile in each other's shoes.
I just don't have a clear idea of what story the author is trying to tell here. There is plenty of various interesting elements. But I can't really see the intent, the vision of the series.
