First time

"Because of the king's command, my dear prince," said the knight.
Second time
The prince said: "Knight, the king is dead, why are you still trying so hard to protect me?"
The knight said: "Because I follow my heart, my prince, and my heart wants to protect you."
The third time, the prince is in danger
The prince said: "Knight, can you tell me the truth now? Why do you try so hard to protect me?"
The knight said: "Because I love you, my dear prince. I love you, so I protect you."
"The vastest, jewel-blue sea I have ever seen when I was a child, those were your eyes."
"Your eyes are not the boundless sea, but the forest far away from the ocean."
"But it doesn't matter, you have me in your eyes. And I am your only sea forever."
