Short story. All interpretation rights belong to Ms. JK Rowling. The reversal is quite unique, so please read it patiently. Friends are welcome to leave comments (I would like to know if your thoughts have been expressed), and I will definitely reply well. PS. I strongly recommend that friends who don't understand it very well the first time read it again (Hey, isn't it a bit shameless?)
Purpose: After fifty-one years in prison, Grindelwald finally understood his own heart.
