In ancient Greece, there was a king named Aegeus. He had a brave son named Theseus. Theseus was so courageous that he decided to go to Crete to challenge the dreadful Minotaur.
King Aegeus was extremely worried about his son's safety. Before Theseus set off, they made an agreement on a signal. If Theseus came back successfully, he would change the black sail on the ship to a white one. In this way, when the king saw the white sail from a distance by the seaside, he would know that his son was safe.
Theseus and his companions boarded the ship and set off for Crete. The journey was full of difficulties and obstacles, but Theseus didn't flinch at all. Finally, they reached Crete and successfully found the hiding place of the Minotaur. After a fierce battle, Theseus defeated the Minotaur with his wisdom and courage.
Then, Theseus, full of the joy of victory, was ready to return to his homeland. However, on the way back, either because he was too excited or negligent, he forgot the agreement with his father and didn't change the black sail to a white one.
When King Aegeus saw from a distance on the shore that the returning ship was flying a black sail, he thought his son was dead. He was so grief - stricken that he felt his world had collapsed. In deep despair, the king jumped into the sea without hesitation. And it was only after Theseus landed that he realized his negligence had caused such a serious consequence, and he was very remorseful.
