The Princess Who Wants to Die.

Goodbye, everyone in my homeland who discarded me, saying I was unwanted. "This is revenge – no one will notice, I suppose." Wendy, the sixth princess, had been forgotten and neglected by everyone in the kingdom since she was born. For the first time, her father, the king, gave her a command: to be sent to a "barbaric" country as a substitute for her older sister. After completely ignoring her existence all this time? After neglecting her, she's being treated like a "cursed child" (a useless pawn)? Therefore, Wendy, who has memories of her past life, was enraged and decided to destroy her homeland. And she decided to die gloriously, in the end.
