A world where people's dreams sparkle
We invite you to the fantastic and mysterious 'Cassiopeia'!

Cassiopeia, another world where all the world's dreams come together! Even the mere appearance of this place is enchanting.
The endless spruce forest, the sparkling red, yellow, and white dream beads hanging from the branches, the Cassiopeia agents flying through the sky in their splendid costumes, the central tower that moves and enlarges the dream beads, and even the multi-functional dream watch – the elements that make up the world of Cassiopeia are all fantastic and surprising.

What happens here really stimulates our imagination.
People's nightmares are caused by a gray spider that crawls into their dream bead, and defeating this gray spider will free them from the nightmare.
To help people escape their nightmares, Cassiopeia agents search the fir forest for red dream orbs that mark nightmares, enter them, and defeat the gray spiders.

There is a girl who has set foot in this mysterious fantasy world of Cassiopeia.
Hara, a twelve-year-old girl! One day, Hara is suddenly appointed as a member of Cassiopeia's first stage. She experiences the nightmares of countless children.

Nightmares are more bizarre and terrifying than you can imagine.
In the nightmare of a child who is afraid of being bullied, a snake flicks its tongue to eat the dream owner, and in the nightmare of a child who encounters a monster from Greco-Roman mythology, a huge earthquake occurs.
Unpredictable crises arise one after another! Hara refuses to give up and uses her wits to overcome the nightmare.
He demonstrates leadership and leads his fellow agents to defeat the Gray Spider, and when attacked by a tornado in an unknown area, he calmly throws his weapon to escape the situation.

How will Hara's challenges and adventures end? The suspenseful, thrilling story will instantly immerse readers.
Children who have been thirsting for special fantasies, come on an adventure with Hara.
This will be an enjoyable piece that will satisfy the desires of girls who want to become a cool protagonist and have a special experience at least once.


One day, I secretly peeked into my friend's inner thoughts.
Friendship and love, what will Hara choose?

One day, while Hara was doing great, she accidentally enters her best friend Sena's dream and learns Sena's secret.
That's right, Sena likes Minjae, who Hara likes! Hara, Sena, and Minjae are always best friends and are so close that the three of them even got friendship rings.

From this point on, Hara's mind is filled with worries about her relationship with Sena and Minjae, rather than the mission of chasing away nightmares.
Moreover, at school, Sena and Minjae enter a dance competition without Hara, and the two of them start to become close.
Swept up in a strange jealousy, Hara breaks the Cassiopeia rules and sneaks in to find Sena's dream bead...


In Sena's dream, the emotions she felt in reality are revived and unfold as nightmares.
While practicing dancing with Minjae, Sena confesses her feelings to Minjae, but Hara appears and interferes with Sena's love, saying she wants to take Minjae.
Sena struggles to give up her friendship with Hara and choose her love for Minjae.
Hara, who had been watching the nightmare, is shocked and feels betrayed by Sena...
In reality, Hara and Sena's relationship becomes increasingly distant and awkward.
Even Minjae neglects Hara, and Hara's heart aches.

Will Hara be able to become a worthy member of Cassiopeia without being swayed by her own personal feelings? What will become of the fate of Hara, Sena, and Minjae, caught in a love triangle?

A confident character who chooses and takes responsibility for his own life.
The images of the girls this era has been waiting for are vividly captured!

This book features characters from the world of Cassiopeia, as well as Hara, Sena, and Minjae.
Jisoo Daewon, a dependable team leader with outstanding skills and a strong sense of responsibility, exemplifies the kind of female leadership this era desires.
And fellow member Somin Daewon, who shows off her quirky charm with her natural curiosity, is a person who knows how to help many friends warmly.
This is also a girl image that is absolutely necessary in our times.

Also, as the Girls' judge commented, "It felt like the girls' love, hate, and jealousy were happening in our classroom (5th grade, Jeong Ga-hee)", the protagonist Hara's struggles and conflicts between friendship and love are just like those of children her age, and seem to accurately portray the appearance of a teenage girl.


Since being appointed as a Cassiopeia agent, Hara has been actively working and doing her best.
Also, when you are in a situation where you are conflicted between friendship and love, think carefully about what is more important to you and make your own choice.

Whichever Hara chooses, it is Hara's choice, and the responsibility for that choice also lies with Hara.
The author does not force you to choose one or the other.
It simply shows Hara's struggles and worries as she gradually realizes the importance of friendship and love.

Readers, looking at Hara's appearance, should think about which one they would choose between friendship and love.
It will be an opportunity to reflect on what is more precious to you.
You will also discover the amazing side of yourself that makes choices, takes responsibility, and leads your life with confidence.
