It's your fifth year at Hogwarts and your brother's seventh/last year. You've changed a lot over the summer, which has not gone unnoticed by your enemy/brother's best friend, Mattheo Riddle.
Disclaimer: English isn't my first language so I'm sorry if the grammar doesn't line up.
Timeline: So it's like the timeline in the Harry Potter movies but with a modern twist so with phones and stuff.
