Game background:
You bought an unnamed fairy tale book in a strange library in a tourist town. It is very interesting. Unlike other story collections, it is more like an adaptation by a modern author.
Among them are short stories about a princess and a werewolf, and a witch who traveled back to modern times. The author's combination of modern times and fairy tales is very interesting, making you read with gusto and forget about food and sleep...
You hold this book all day long until you fall asleep. When you wake up, you unexpectedly find yourself in a fairy tale!
And all the girls are falling for you, what a great thing! ?
