This is a story that feels like a dream to the protagonist.
The people and things in the dream were far, far away from her.
However, those people in the dream really existed, and those things really happened.
Some things, perhaps, are really because you can't forget them, so you seem to be living in that dream all your life and don't want to wake up.
Purpose: Family, country and love complement each other. In the decades of the Republic of China, there were too many heroes, but maybe heroes also have regrets.
