An ant in the world of immortals, he endures hardship and bides his time, yearning to rise above his station, yet finds no path to heaven and no way forward. An ordinary person in the world of Blue Star drifts through life, going with the flow. Though he lies flat and takes things as they come, he still cannot let go of his regrets. One soul, embodied in different worlds: what will happen when those lives meet one day? How will one soul, two worlds, and two bodies choose their path through life? A mortal can become an immortal, and an immortal can be ordinary. A mountain need not be tall, nor even exist: if there is a mountain in your heart, you are an immortal.
