I have always been wondering about the place. The place where every inexplicable thing happening to me started. That place where I became a person different from anyone. Together with Ana and Seline, we are given the gift of becoming mermaids. Sometimes we are there, sometimes we are not. We have been finding each other for how many years. I have kept my secret for many years. Until my life entered college. I had never thought my secret will be challenged like this. It is the point of my life where I finally understood reality and magic. It is the point of my life where I found Ana and Seline. Together, we keep our unexplainable secrets to anyone, to anyone we love. I am Grace Joy, a student of Horizon Reached University. I am Grace Joy, a mermaid awakened between two realities. I am just a girl trying to find love in spite of my mysteriousness. I have a deep secret. Can we keep our secret forever?

Grace Joy is a girl who is no ordinary, unlike any other girl. As she tries to be normal, she keeps her extraordinary secrets to the people she knew. But when she entered Horizon Reached University, she found out that not only she possesses such secret. As she enters college, she will face the dangers that are prepared by fate that she had never experienced in her previous years. Can she keep her secret from the people around her?
