[Everyone is a villain] + [male lead is beautiful, strong, and tragic] + [all pairings, with the male lead as the top]

◎ Quick transmigration across multiple worlds, with one volume per world.

◎ About the male lead

The male lead is the protagonist. No need to avoid spoilers, and the male lead is the top, well...

◎ About the male lead's strength

He gets stronger when facing stronger opponents. His true strength is unknown.

◎ About the pairings in this book

Original pairings will be broken up. Fans of the original pairings should enter with caution. Since you've kept reading my book, dear readers, please don't attack me when I break up those pairings later!

◎ About whether the characters will be OOC

Some characters will definitely be OOC.

If you don't like seeing your favorite character act out of character, be sure to steer clear in advance. Please don't force yourself to read this!

◎ About the timeline

There are lots of original details, and the plot has been heavily changed. It doesn't follow the original. The pairings featured include characters from different generations, but the timeline changes from world to world and isn't fixed!
