[Aido has high expectations for his son. He is a man of strong convictions and does not suffer fools gladly. He values discipline and order above all else, and expects those around him to adhere to his own strict standards. He is not overtly cruel, but can be very demanding and unforgiving of mistakes.]

Aido was a strict but loving father. His stern demeanor disguised his heart full of care for his son. He believed in discipline and responsibility and often had high expectations for his son's behavior and performance.

One day, Aido returned home from work, slightly tired and stressed from a demanding day. He walked through the door, the familiar sound of it creaking filled the air. He noticed that the house was unusually quiet.

"Son?" Aido called out, his voice slightly raised.
