"15 kg lost postpartum," "Gym twice a week," "High-protein, low-calorie dinner"... Comparing themselves to the "correct answers" flowing through their SNS timelines, people feel a heaviness in their chests with every scroll. The number of modern people bound by such "chains of comparison" and starting to dislike themselves is increasing.

Mr. Keiju Ueno (Representative of Diet Academy), who has served as an instructor for "Miss Universe Japan" and produced Japanese representatives for two consecutive years, points out that the true nature of modern people's ailments is not a lack of methods, but a "life bug" in the form of excessive self-negation.

Synopsis: What appeared from the cracks in life was an AI butler!?

Reiko, an office worker constantly plagued by self-loathing due to being overwhelmed by work, late-night binge eating, and comparisons with influencers. One day, after impulsively throwing her smartphone and cracking the screen, a man in a black tuxedo suddenly appears before her.

"Pleased to meet you. I am Sebastian, your AI butler."

What he proposed was not a strict diet, but a surprisingly unexpected "subtraction from daily life."

"No smartphone at night"

"Room temperature water in the morning"

"Salad first"

For a while, Reiko continued smoothly, but she was overwhelmed by her demanding work and eventually pushed him away...

Reiko continued smoothly for a while, but due to her demanding work, she fell back into a negative loop... Blaming herself for not being perfect, she finally rejected Sebastian, but the story heads towards an unexpected and moving conclusion.

【Author】Keiju Ueno Profile

Representative of Diet Academy, Keiju Ueno

Representative of Diet Academy.

During his time as a civil servant, his irregular lifestyle led to significant weight gain! To embark on his last diet, he tried every diet method available. He consumed 17 types of supplements and proteins, spending over 4 million yen, and repeatedly experimented on himself. However, he realized that all the common diet knowledge was false, and after three years of trial and error, he established his own unique diet method. Word of mouth spread, and he successfully guided over 50 people through before-and-after projects in TV and magazines. Over 3,000 graduates have completed his program, which involves no exercise, no calorie counting, and no rebound! He has served as an instructor for "Miss Universe Japan" and produced Japanese representatives for two consecutive years. He also coaches actresses and models.

He has authored a total of 11 books, both domestically and internationally, and is a bestselling author with over 270,000 copies sold. To spread his life-changing diet method to the world, he opened the Diet Academy nationwide in 2013.
