All human relationships are useless.“No matter what happens to the original story, I plan to live with cats for the rest of my life and then die of old age.”So, I decided to stay at home. The so-called Emperor Self Imprisonment.You have so much money, why do you leave?In order to live a comfortable life in confinement, they spend a lot of money making tape recorders and gramophone magic tools, but something is strange.
