Puppet Smile

The life of mysterious twins, a sister with a secret, a younger brother who wants to kill his older brother and an older brother who knows the truth. With the help of a third party, several people face the cold rules of the magical world. One is an outsider, one is absconding, one is missing, and one is both good and evil. Who is carefully weaving this web of destiny, who breaks the worldly fake smile, who silently guards the rising hope, and who makes the puppet's smile come from the heart?
