Min-Ji is a 16-year-old first-year high school student. She's a huge fan of romance novels. One night, she has a vision: a god forces her to travel to another world, completely different from the one she knows as Earth. There's no technology or communication devices; instead, there are all sorts of wild beasts masquerading as hybrids, from dragons to mermaids. In this world, magic also exists... wait, if you don't have mana, you're doomed, because you need at least 1%, which is what most people in the nations possess. And if you don't have it, get ready, because you'll become... a slave. but... She didn't die in her past world; at least, in the stories she read about reincarnation or transmigration, death was a prerequisite. So why did the god send her to that world...? Oh, right, he needs her to complete a mission. Once she's finished, she'll decide for herself whether or not to return home. But Min-Ji desperately wants to go back, because she has a mother who loves and cares for her dearly, and also her best friend, with whom she shares many fun and happy times.
