Souls and Brothers

It's Albus Severus and Scorpius Malfoy's fifth year at Hogwarts.
Scorpius recently got over Rose Granger-Weasley. He realized he felt nothing for her anymore. He tried going out with other girls, but he didn't feel any sparks.
But recently, he's been thinking about his best friend a lot, recently. Whenever he thinks about him or sees him, all he can think about, is kissing him.
Since the Chapmans and the Malfoys are family friends, Polly and Scorpius see each other quite often. This means that they both know they have feelings for Albus.
Polly suspects that Scorpius fell in love with Albus. Scorpius denies it, but knows it's true.
In order to get her childhood friend to confess or come out, she starts making moves on Albus. This starts a riff between Scorpius and Albus.
