Irene, a lost princess who is locked on a tall tower. She didn't know she is a princess. The witch, or from what Irene know, her mom, locked her in a tower saying that she'll die once she step out of the premises. She lived a very lonely life. The only person she get to see in her all life was the mother she knew.

In her desperation to make her loneliness disappear, she waits for a shooting star every night, to wish for a companion, other than her mother, to be with her, forever.

And that wish came true, in a form of a girl named Seulgi, who was stuck in her own dream.
