Ascending to the Divine Throne in an Old-School Mary Sue Novel

[Transmigrate into a book + ensemble cast, to a degree + heroine's perspective + old-school novel]

Also titled: I Became One of the Mary Sue Heroines, and Ascended to Godhood by Playing an NPC

[Before you start]: This idea came from all those “noble young master vs. assassin girl” stories I read as a kid. I'm writing this purely for fun, so please go easy on me (please, I'm begging you, hands together.jpg). This book ends here; see you in the next one~
