"Harry Potter" text
Protagonist: Lin Mo (white and black, high talent)
cp: Snape
Introduction: Lin Mo went to the world of Harry Potter and knew the entire future. After entering Hogwarts, he embarked on a journey to make up for his regrets, and never returned on the road to protecting Professor Snape. (Not bad for Dumbledore)
The writing is immature, so please forgive me.
The protagonists are strong, redeem each other, and have a happy ending.
Purpose: to make up for regrets
