Lia

As Liam, he went to the beach almost every day with his friends. As Lia, we can assume she does much the same, only now with a sense of mutual attraction. She is the protagonist of Silly Wish.

In Silly Wish
At the beach one day, one of Liam's friends found a very shiny jewel, and one of them claimed that it would grant one wish to the user, and also do something else, either logical or entirely unpredictable. Liam called dibs, and jokingly wished for pink hair, not really believing the story. The jewel obliged despite his non-belief, giving him pink hair, along with a blue bikini, large breasts and... yeah. Re-christening herself Lia, the woman noted the important moral she had learned.
