They are silent and gentle young men, with bright and clear eyes, timid and simple hearts. One is a top student, and the other is a classmate. One is silent and gentle, following the rules, one is serious and strong and abides by principles, one pretends not to know, and the other is careful to test. One is a turtle with a shrunken head, and the other is a closed clam shell. They live in the same sea, but they never fall in love. They live in the same world, but they cannot be together. They both dare not be brave for love. They are both complete cowards.
