When Time-Travelling Piano Was Mixed up in Harry Potter

When Harry Potter has the power of Gin, or in other words, Gin becomes Harry Potter, what will happen to everything? "Gryffindor!" The Sorting Hat called out the house where Harry would be. Harry showed his signature gin smile and said, "Well, Gryffindor, right?" He successfully scared a bunch of little lions and other small animals who were about to cheer. "Is the sorting hat broken? With this smile, it seems that Harry Potter should be sorted into Slytherin!" By a bunch of frightened little animals. Ps: Do you think this is the real situation? No, the whole text is nonsense. Ps2: The protagonist is not the real Gin, he just has Gin's memory and abilities. Ps3: The writing is poor, please forgive me. Intention: To generate electricity for love, I want to give the professor a different ending.
