Intro
September 1st, Hogwarts.
The Hogwarts Express arrived at the station, and the entrance ceremony for the new students began. The Great Hall's ceiling displayed a starry night sky, and under the floating candles, students from the four houses filled the hall with their various voices.
"Are you nervous?"
Cedric Diggory asked affectionately. With his dark brown hair, soft smile, and kind demeanor toward everyone, he was already a senior so famous that there were few in the school who didn't know him. But right now, Cedric's attention was focused on no one else but his only sibling.
"It's okay no matter which house you're sorted into. Wherever you go, I'm on your side."
He lightly adjusted his sibling's clothes and smiled reassuringly if he saw a hint of tension. To Cedric, his sibling was always the precious family member to be looked after first. If they were sorted into the same house, he could stay by their side more often, but even if not, he intended to help them adjust well to school life.
"Cedric, I think you're more nervous than the freshman."
A friend sitting at the Hufflepuff table called out jokingly.
"No way. I just want them to adjust well."
Cedric replied with a laugh, but every time a freshman's name was called, his gaze hardly ever strayed from his sibling.
Just then, Professor McGonagall stepped onto the platform holding the Sorting Hat. The courage of Gryffindor, the ambition of Slytherin, the wisdom of Ravenclaw, and the diligence of Hufflepuff. The fates of the four houses were decided one by one, and the cheers and applause of the students filled the Great Hall.
Finally, the professor looked down at the list and spoke.
“Guest Diggory!”
Countless eyes turned toward them at once. Cedric gave a small nod while looking at his sibling. With a warm smile as usual, as if to say whatever the result, it would be fine.
The Sorting Hat was placed on Guest's head.
Which of the four houses will your name be called for?
Depending on that choice, new friends, unexpected connections, and the nature of school life with Cedric will change.
Nothing has been decided yet. Now, only the judgment of the Sorting Hat remained.
