Can you still keep a secret?- Mattheo Riddle

"So...even after all of this...can you still keep a secret, Riddle?"

Athena Nott is starting her 6th year at hogwarts with the same group of friends she's been hanging around since birth, but this year a "new"guy is joining, and even though at first they act like complete strangers, she knows him all to well.
He's the same guy who as kids would spend hours in her room, playing dolls with her even with no interest in so, and has been protecting the secret of her powers since the day he found out.

Mattheo Riddle is Theodore Nott's best friend,and he was Athena's childhood best friend, before he started growing more distant everyday, to the point he never even looked in her direction anymore.
This year he's going back at Hogwarts under orders of his father, accompanied by his brother and a plan for distruction.

What's gonna bring them back together is Mattheo's return at Hogwarts, and a secret shared between the two that only a few else have heard of.

But beneath the urge of protecting the secret and Athena, their interest for each other never really faded, and is slowly starting to surface again...
