Kim Jumi's life is like that of any other teenager preparing for her CSAT's: all work and no play. But one summer day, she witnesses something on the rooftop of her school... From then on, she finds herself getting tangled up with two boys who are in a complicated relationship.

Three students are living fairly normal lives when, one day, they are overcome with intense stomach pain and a star symbol appears like a tattoo on their skin. With the symbol came supernatural powers, as well as enemies coming to kill them.
