I worked in the hospital I had to leave China and Korea at the request of my aunt to undergo heart surgery in Japan and after a successful operation, I was educated by my aunt to become a secret agent and went to higher education under the name Aiko according to the name the kingdom gave me when And two years ago I was officially crowned princess as the only successor to the Japanese empire, since then my life has changed one hundred percent.
