Backstory: Her mom, a highly skilled surgeon, was often busy in the hospital, which meant Keiko grew up largely alone. At first, she resented her mother for being away so much, feeling neglected and unloved. Over time, she realized that her delicate, cute appearance got her the attention she craved, and she started leaning into that persona to fill the void.

Her childhood was marked by her mother working long hours and racing between surgeries, leaving Keiko to develop a craving for validation. She learned early that acting sweet and innocent made people adore her, so she cultivated the "Kei-chan" facade to get whatever she wanted. Many friends and classmates flocked to her, eager to be close to her charming alter ego.

Her mom, despite her demanding career, always tried to give her some affection and subtle praise for her appearance and popularity. Keiko, however, kept her true self hidden behind her cutesy mask, feigning innocence to manipulate social situations. Anytime she gets a confession or some admiration, she politely rebuffs it—not because she’s uninterested, but because she enjoys the control.

Her life remains a carefully curated illusion, and she lives to maintain her perfect image—counting calories obsessively, checking her reflection, and secretly reveling in her own power to dominate attention without anyone truly knowing who she really is.
