In this world, there are extremely powerful amulets that humans can obtain and control and use to whatever extent. Of course, there are limits, but to an idol (who are humans with powers of their own), it's unlimited.

Meanwhile, Seulgi is an extremely poor girl who lives with her family in a small hut out in the countryside. One day, while she is planting apples trees, she digs up an old and rusty amulet. And ever since she found that amulet, her life has changed drastically.

On the other hand, Irene is a rich girl who has great control over her amulet. Irene is beautiful and popular and is very idolized. Despite all her benefits, her family is scattered. Her parents always have fights physically, some fights even come to the point where they use their amulets. It wasn't until she meets Seulgi that her life changes.
