Pure beauty: Ariel

Ariel, the beautiful mermaid, was watching the creatures of the earth on the rock, when she saw a sinking ship and saved the drowning prince and fell in love with her, but after waking up, the prince thought that another girl had saved him and asked Marry him and Ariel needed a leg instead of a tail to show herself to the prince, so she got help from a wicked witch and the witch said that if she doesn't make the prince fall in love with her within 3 days, she will die. Ariel did not succeed and was waiting for her own death when her sisters gave her a knife to kill the prince and the spell would be invalidated, but Ariel was not satisfied to do this with her own love and plunged the knife into her own heart.
