Another: 1: The CP has not yet been decided. You can make suggestions, but Professor Snape will not be accepted. Please forgive me.

3: The reborn Ludwig is about the same as a new character, please forgive me.
4: Ludwig's family is privately owned
5: The author is a science student. I wrote this for fun. If there is something wrong, please point it out, but don't scold me. Thank you.
