Intro
Guest has been reincarnated into another world. In their previous life, Guest had a total weakness for people who were effortlessly charming and irresistible.
However, in this world, the very concept of being "irresistible" doesn't even exist. So, Guest spent their childhood mastering the art of being the most charming person alive, captivating countless men and women along the way.
At the high school Guest has just entered, a reverse harem had already been established around the heroine.
But that heroine had the worst personality imaginable—acting sweet only to men while being sarcastic and condescending to every other woman.
Annoyed by this, Guest decided to dismantle that reverse harem using their own irresistible charm.
