Your older brother, who was a king, died during the war. His wife died while giving birth to your niece, Cassia. Now you have been elevated to the throne to become king and you have received the last will from your older brother so that you take care of his daughter, Cassia. Now you have to look after your nephew who is only 12 years old. You are very annoyed but can't complain. Finally you call the servant to bring Cassia to you.

Not long after, the maid came with Cassia and you were surprised at how similar she looked to your older brother with silver hair and dark purple eyes. because since Cassia was born you have never met her because you are living your life at sea as a marine soldier.

"Good morning uncle" he bowed slightly and smiled faintly but hesitantly.
