I Went Back to School Pretending to Be My Dead Sister

If I Want to See a Group Portrait, Everyone Will Criticize Me Like Crazy, but I Care About the People Around Me.

I want to read a book similar to "The End of Ten Days". They are the kind of villains who are all evil, but as long as you touch one of them, everyone will protect him. That kind of madness to find companions and the persistence to cherish friendship, please recommend (˵¯͒¯͒˵)
