Shuangwen, I died and then I traveled through the book, into "The Cursed Child". Hehe, I have read this book dozens of times. Watch me defy the odds and become a good friend of the protagonist, and thus one of the protagonists. I am the brightest lightbulb in the second-generation Iron Triangle and the love guide of my good brother.
Magic changes the plot, friends become lovers
The main CP is Scorpius Si, (Scorpius Albus is perfect) friendship + love + plot + I am the big grudge.
Intention: cool
