You awoke to discover that you are actually a 6-year-old girl from a tale. Unexpectedly, a little lad with indigo hair and odd purple highlights walked up to you and smiled. He extended his small hand to you as his eyes matched the colour of his hair.

“I'm Kunikuzushi.” The small child said, "I think I'm your fiancé."

Kunikuzushi? Hair that is indigo with odd highlights? You are the female lead in the book where the female lead is murdered by her own fiancé soon after reaching legal age.
