The inspiration for the story was a dream I had one day——
The love, hatred and hatred of children in the world.
The protagonist is a couple. The husband has practiced the "magic skills" given by his master. He is very strong in martial arts but will not have children. Out of revenge, he insists on marrying the master's only daughter.
This is the story of a couple who seem to be inseparable but share the same bed but have different dreams and love each other.
