I Became the Mastermind Who Betrays the Heroines Light Novel

I transmigrated as the hidden mastermind who betrays everyone at the story’s end.

Since I wasn’t particularly interested in the destruction of the world, I was just leisurely waiting for the ending…

“You’re the only one who truly appreciated my drawing of a snake.”

“When I make plans to meet you at 4, my heart starts racing from 3… Is this what it means to be tamed?”

For some reason, the heroines keep showing interest in me.
