『I Was a Lazy Girl Who Failed at Everything, But My Bugged Life Is Being Fixed by an AI Butler.』 by Keiju Ueno, released on April 30 (Thursday).
Yugeisha Co., Ltd. (Headquarters: Shibuya-ku, Tokyo) announced today, April 30, 2026 (Thursday), the nationwide release of "I Was a Lazy Girl Who Failed at Everything, But My Bugged Life Is Being Fixed by an AI Butler.," the latest work by Keiju Ueno, representative of the Diet Academy and a bestselling author with over 270,000 copies sold, at bookstores nationwide and online bookstores such as Amazon.
■ The more you pursue "the right answer," the fatter your heart becomes. What are the "life bugs" that plague modern people?
"15kg lost postpartum," "Gym twice a week," "Perfect high-protein meals"...
Every time you open social media, someone's "sparkling right answer" jumps out at you. Comparing yourself to them, sighs escape with every scroll. Modern people who are bound by such "chains of comparison" and unconsciously wear themselves out are endless.
Keiju Ueno, the author, who gained significant weight during his time as a civil servant, repeatedly conducted "human experiments," trying every diet method available, drinking over 17 types of supplements and proteins, and investing over 4 million yen of his private funds.
However, no matter how much money he spent or how much he chased conventional wisdom, his mind and body never truly became balanced. After three years of trial and error, he realized the truth: it's not about "what to add" but "what to discard as a bug."
This book is not just a weight loss method; it is a self-help novel of tears and hope, presented to everyone who wants to fundamentally "reboot" the mental distress that modern people face.
