One is a man suffering from affective disorder, and the other is a boy suffering from autism. They are father and son, and their worlds are both cold.
The arrival of a woman brings them back to the normal world, where they can experience the warmth and coldness of the world, not just the cold. She is like the hot sunshine, driving away the coldness and warming their world.
No one thought that one day they would feel: The spring sun is warm and sunny every day, and everything can be hoped for! Who warmed their hearts?
(Lightning protection: The male protagonist's son was a test-tube baby under the calculation of his parents, and his mother was willing to do it for money. Because the male protagonist did not love her, she ran away with the money given by the male protagonist's parents.)
Intention: Be yourself, look down on the results, and have a clear conscience.
