An HP Fanfic (The Dark Lord and the Principal)

It is a GGAD fanfic of the HP series. The general content is that Grindelwald prevented Ariana's death by not using the Cruciatus Curse on Albus in the valley. How will Albus deal with Grindelwald who is gradually revealing his true nature? The characters belong to the official, and the OOC belongs to me. Free 10,000-word short story. I hope you all enjoy reading it. (Demining: This is a work on grain production when I was in school, with an ancient style) Intention: Believe in love!
