An incredible story happened to high school students Han Suri and Ыn Ryu. After a car accident, their souls and bodies separated and started to live on their own. But if a body can continue to exist calmly without a soul, the soul will disappear within a week. The souls of the young people need to find a way to overcome the invisible wall blocking their path to their bodies. Help will come from the instructions of the Soul Guide—a mysterious messenger from the other world.
Now they can better understand themselves and their problems. Han Suri tried with all her might to be the best in everything, while Ыn Ryu deeply hid his suffering, feeling abandoned by his family. Will the souls of the young people have time to return to their bodies, or will they follow the Soul Guide into another world? After surviving all these terrifying trials, will Han Suri and Ыn Ryu be able to change their views on life, accept and forgive themselves and the people around them?
