Brilliant Lives Passed Over in a Single Stroke

If no transmigrator rewrites the script and no outside force forcibly changes their course, are the characters etched in our memories really doomed to follow their set destinies to the end?

Including, but not limited to the following (the order may change, but I will definitely write them):

Harry Potter: Cho Chang and Cedric (completed)

Harry Potter: the twins

Harry Potter: Draco

Harry Potter: the Marauders and the aunt

A Smile Is Beautiful: Zhao Erxi

Scarlet Heart: Yu Tan

The Return of the Condor Heroes: Guo Fu (in progress)

Crossover world: Meng Yichen and Chen Meijia (completed)

Phoenix Nirvana: Ye Cunxin

No More Bets: Anna

Sandstorm: Liu Yingying
