At the end of the story, I found myself in the body of a hidden villain, betraying the heroines. Since I’m not particularly concerned about the end of the world, I’m calmly waiting for the finale… “You’re the only one who truly appreciated my painting of the boa.” “When I make plans to meet you at four, my heart starts racing at three... is this what they call being tamed?” For some reason, the heroines are starting to take an interest in me.

Childhood sweethearts.
The most popular person in school is my childhood sweetheart.
