It's a story from my middle school teacher. A fisherman makes a living off the sea and he loves it so much. A noble lady falls in love with fisherman, who, does not want to leave the sea. The fisherman marries the noble lady out of sympathy. But six days later, he sets sail again and never comes back.

When a person has a deep feeling for something, his heart probably remains unmoved even if there are more attractive things around him.
