This is a not-so-good story.
Love, friendship, and family affection run through the protagonist's life. He is a "bug" who lives in the background of that feudal era.
What many people will see is that he lived an imperfect life despite being nearly perfect.
He has always been a fool...
He was busy running between relationships, and they all ended in failure. He had also liked and loved with all his strength, but there was still no result. Later, he changed, became tired, and no longer wanted to act even though he had devoted his feelings...
Purpose: I would rather fly to a flame than to speak in the secular world
