Do you know what point X is? That is, you have been living in your own parallel world. It is a straight parallel line. Suddenly, there is an extra point, connecting another unrelated parallel line. The originally parallel world begins to become more and more curved and winding. In the end, the two lines blend together and are inseparable.
Concept: A man named Parallel was raised as a substitute for his father by his mother who lost his father. He has no soul of his own and meets his own X-point. He uses the evil in his bones to get closer to the X-point and engulfs her bit by bit.
