Luke is infatuated with the boy with locker number 2537.

"As though in a trance, the little mermaid clasped the knife and entered the cabin where the prince and his bride-to-be lay asleep. But as she gazed at the young man's sleeping face, she simply blew him a furtive kiss, before running back on deck. When dawn broke, she threw the knife into the sea. Then she shot a parting glance at the world she was leaving behind, and dived into the waves, ready to turn into the foam of the sea from where she had come, and vanish." ― The Original Tale of the Little Mermaid
