Seeing a True Person from Inside (Jay x OC)

In the United States of Auradon, there lived a princess named Adelissa "Adel" Lynae Beast, the younger twin sister of Prince Benjamin "Ben" Florian Beast. Although she has her mother's interests and beauty, Adel takes after her father more. However, most of the citizens of Auradon don't know that she can turn into a beast like her father once had, which happens when she strongly feels emotions like anger. This is one of her gifts from the Enchantress since her and Ben's birth, something she often considers as a curse from nearly becoming a 'monster' each time her temper gets out of her control.

On the Isle of the Lost is Hayes Ignatius, the son of Maleficent and the younger brother of Mal. He impresses his mother more than Mal tries to, but the siblings remain close. Just like his sister, he wants to prove himself to their mother. Being her favorite child for being evil more successfully is a goal Hayes keeps secret from everyone except his sister since the day he moved to his mother's castle, though it helps him wanting to prove himself more than anything alongside Mal throughout their rotten lives.

Nearly at the age of 16, the soon-to-be new king and queen of Auradon make their first royal proclamation: to give the children of the villains a second chance by inviting them to attend Auradon Prep. When the evil siblings found out the royal twins picked them and six of their friends to attend Auradon Prep, their mother gives them the task to steal Fairy Godmother's magic wand. But how will Hayes do it when his new life in Auradon slowly changes him? How can Adel handle her beastly gift with the aid of her new friends? And what is going to happen between her and a certain flirtatious but handsome thief, who may see the true beauty within the she-beast?
