Two smooth circular patterns accidentally bumped into each other, and the overlapping area is the only mark that can distinguish the two circles. However, possessiveness and scheming continue to fill each other's lives, and in the end it is only the overlapping area that suffers the greatest harm. This is a war that has no end. If the overlapping area is no longer there, the two patterns become one pattern. If the pattern is completely separated, the overlapping area that was created by it will no longer exist.
