The protagonist is Ralph Esteson, a reincarnated person. Even as a child in his past life, he had an unnecessarily sharp mind and overly keen hearing (practically superhuman hearing).
Instead of being swayed by the “World Administrator” schemes that would entice ordinary people, he used them to his advantage, taking a “cheat” as a souvenir when reincarnating into another world, and starting life anew as a baby.
He spent 15 years in the peaceful life of a fallen noble and then entered the Royal Magic Academy at 15. Two months later, he graduated early. He set the “fastest in history” record.
After that, he became an adventurer and lived a lazy life, until he met a prostitute (the heroine) in a brothel by chance, bought her freedom, married her, and now spends his days flirting and being intimate with her.
