The protagonist awakens in a luxurious, unfamiliar room, attended by numerous maids who address him as "Young Master." He is utterly bewildered, as this opulent setting is a stark contrast to his ordinary life as a high school student. A beautiful, silver-haired maid named Kyoko explains that they serve "Hazumi Reito," a name the protagonist doesn't recognize. He suspects he has transmigrated into an "evil villain" role, a common trope in novels where the protagonist is reborn as a character destined for ruin. Determined to avert this fate, he resolves to break all "destruction flags." However, he lacks crucial information about the world's scenario, the villain's identity, the heroine, and the protagonist.
Upon examining his reflection, he confirms his new appearance: a handsome, slender boy with black hair and sharp blue eyes, though with dark circles under his eyes. He deduces he's in a modern setting, not a fantasy world, and believes he's a villain in a modern romantic comedy. A female doctor is called, and during her examination, she asks him questions about his name, age, and life. He learns his name is indeed Hazumi Reito, he is 15 years old, the only son of a wealthy family, and lives in a mansion with dozens of maids. Despite his supposed villainous role, he is treated with great care, which puzzles him. Kyoko remains suspicious of his changed demeanor and speech.
The protagonist decides to gather information about the original Reito and Kyoko. He learns Kyoko is 20 years old, a diligent maid leader who also supports Reito in his education. He also discovers that the original Reito was a spoiled and arrogant "Young Master" who treated maids poorly, even engaging in sexual harassment. This behavior is attributed to the world's societal structure, where men are scarce and highly valued, leading to overprotective and sometimes aggressive behavior from women. Kyoko, who dislikes the original Reito due to his behavior and a past family connection, was hired as his personal maid to manage him.
The protagonist, aiming to raise Kyoko's favorability, begins by performing chores like mopping the floors, a drastic change from the original Reito's behavior. This unexpected action causes confusion and a slight shift in the maids' perception, though Kyoko remains wary. He also starts training his body, believing it's essential for survival and to break his villainous fate.
Kyoko, observing Reito's changed behavior, is concerned about his lack of awareness regarding the dangers of the world. Due to the extreme gender imbalance, women are often aggressive towards men, and Reito's current naive demeanor makes him vulnerable. Despite his requests to go outside, Kyoko initially refuses, citing the danger. However, she eventually agrees to take him out, but only by car, and they visit his future high school. During their outing, Reito notices the overwhelming presence of women in public, a detail that further solidifies his understanding of the world's unique gender dynamics. He realizes that his perceived "villainy" might extend beyond the mansion, and his safety is a genuine concern.
