SAISAKU ;; that never existed
The first time Sakura saw Sai after he voluntarily left Team Kakashi, he was stark naked and shoulder to shoulder with approximately a dozen other nude men. They had the decency to be embarrassed as Sakura poked and prodded, asking the invasive questions required of their yearly physical and blushing heavily when she politely asked that they cough twice while she supported their testes in the palm of her hand. It was all very clinical for her; they were the fifth group she had seen so far and it had been years since she had considered the process of a hernia check awkward. Some things just stopped phasing if you did them often enough, and administering physicals was one such thing for Sakura and any of the other nurses and medics in the hospital. Although Sakura mused she could at least try understand why it bothered her patients. She saw any number of naked shinobi throughout the day during annuals.
They saw just one pretty nurse.
"Hey there, Ugly."
"Sai," Sakura said tersely, adjusting her stethoscope to listen to his breathing. His breath hitched with what Sakura assumed was supposed to be a laugh. She raised an eyebrow at him curiously
"No one's called me that for quite some time," he said flatly as Sakura went about her jabbing in his ribs and bending his arms and legs in examination of his joints. "Not since that mission ended."
"That mission," Sakura repeated. "Of course."
Team Kakashi had just been a mission for 'Sai,' the boy that never existed.
He gave her a false smile when she reached to cup him in her palm, "Feel free to use both hands if you need to ~"
Sakura narrowed her eyes, "Not necessary. Cough twice."
He did as he was told.
