Flowers That Wilted: Evans Family Story [Fred X O.C. X George] A triad

Lily had been messing with James for years, playing the cat and mouse game every time he got into a new relationship. When he would go back to her, she would drop him.
She finally crossed the line when her twin-Petunia-had started a relationship with James. They were set to marry when Lily slept with James and fell pregnant.
Doing what he thought was correct (Despite always wanting Lily), he left Petunia-lying to everyone that she cheated on him. Little did he know the lie would become unraveled years later.
He also left two special gifts behind.
Ivory and Dudley Evans got their Hogwarts letters and the wizarding world all believed that they were muggle-born.
Harry has half siblings that he believed were just his cousin.
