Hoshino Ruri had a nasty personality, and before being reincarnated, he was already one of the homewreckers.
When he reincarnated, the goddess not only spared him punishment, but even granted all his wishes: to become the heroine of an NTR story and enjoy the thrill of breaking the cuckolded man's mind.
Reborn as a female infant, he had a gentle childhood friend cultivated since kindergarten, an athletic girl he met in elementary school, and a literary girl he met in middle school.
Hoshino Ruri decided to shatter the minds of those who loved her during high school, turning their affection into hatred to satisfy himself.
--But this is a world where everyone wants her to be happy.
