The Story of Rhodan
Our cynical protagonist has woke up as a character into a popular manga; The Story of Aron which had reached its end. Not just any random character though, she is transmigrated as the protagonist's pitiful mother. After she changed her name thus having her own identity, she is set on completing her mission to go home and making sure that the story doesn't stray but still changing her character's fate.
The Ending of a Story
The last thing she could remember vividly from her old world was finishing the last volume of a story called The Story of Aron.
To summarize, it is about a boy who grew up being ostracized and was mostly alone until he was found and adopted by his master and father figure until he died. The boy took on his name as his own giving him the name Aron without the extra 'a'.
Up until the end, he has been through trials and tribulation, loss, character development and despite the seemingly cheesy progress, it does have its good points.
There is a whole list of interesting and unique characters who are both meaningful to the story and loved by the readers and the story is greatly impactful to the point where she has shed many tears over it.
What she didn't expect though is that she will become a part of it.
