"Sakura, I'm afraid you won't be able to help in this ward. Lady Tsunade has requested to give two special check-ups today." The receptionist informs Sakura. The cherry haired girl nods dutifully and follows the receptionist/nurse to an examination room.
"The kazekage? I'm performing a check-up on Gaara?" Sakura exclaims, reading her patients name on his medical file. She receives a curt nod from the nurse who scurried away quickly. Sakura gulps once, tidies her medic-nin outfit and composes herself. With a deep breath, she pushes on the doors and enters the room. The scarlet haired young man sat patiently on the examination bed, arms folded across his chest. "Kasakage-sama, I am Sakura, I will be attending you in place of Lady Tsunade. Please remove your shirt and I'll be with you in a moment." Sakura says calmly. She turns as he undresses and places a stethoscope to her ears.
Naruto's teammate. Gaara thinks, his bitter eyes following her with distrust . He had almost killed her in the past at one point in time. She isn't afraid of me-different… Gaara stays completely still a Sakura positions gentle fingers on his chest, placing the stethoscope on his heart. "Your heart rate is a bit fast…there is no need to be uncomfortable."
"Do you mean that or are you simple reassuring yourself?" Gaara's cold voice questions and Sakura stares at him serenely. Then she realized the kage was joking because a corner of his mouth had lifted in a small smile. Gaara makes no further comments, but his eyes follow her as she writes down notes on the given clipboard. Gaara is not used to being near people, he doesn't know exactly how to act but his older sibling had given him some counsel when speaking with a female. The only advice he could recall lead him to seeking for a compliment to suit the nurse attending him. She has many unusual qualities, A strange name, a large forehead, pink hair…but he chose her voice.
Sakura had never felt so discomfited as she was now. Gaara had praised her voice, saying it was like his mother's. Sakura had found herself smiling sweetly until the conversation revealed that his mother is dead. "I would say I'm sorry for your loss, but experience taught me people find that annoying." She tries not to blush as she asks if the Kazekage was having any trouble urinating. Gaara mumbled a no. "Stool?" Another reply in the negative. "Please step onto the scale." She orders politely and he complies. She also measures his height and continues by following her normal procedure, writing down the results of her assessment. "Gaara, you appear healthy, although your suffering from weariness, I suggest a few nights rest-"
"I don't sleep." Gaara states and Sakura nods, taking this down. She writes a prescription for a mild sleeping medication. "Also, you seem a bit low on essential vitamins from malnourishment. Make sure you consume three full meals a day and drink lots of water…Your purpose as Kazekage is to look after your people, which you cannot do unless you look after yourself. " Gaara's eyes widen. It's as if she actually is concerned about his wellbeing…
"That will be all, and I hope your visit wasn't too unpleasant…" Sakura gives him a kind smile and bows as he slides back into his robes and exited the room. She hands her notes and the medical file to the awaiting nurse outside and was quite happy. Until Uchiha showed up…
The nurse guiding him to the room clearly adored him. Sasuke ignored her flirtatious banter as he entered the room and took a quick glance at a glaring Sakura. "Hello Uchiha." He gives her a nod of acknowledgement and leans against the examination bed. Sakura repeated what she had said to Gaara, telling him she is replacing Tsunade and for him to disrobe the upper-half of is body. The arrogant git blinked twice in reluctance, contemplating whether or not to remove his robe. "Uchiha may I remind you that I follow this procedure with many men, I am a professional and you no longer have to fear me having feelings for you. Now stop wasting my time…"
Sasuke raises the shirt, revealing a masculine chest. Sakura couldn't actually believe he hesitated, thinking she still possessed a childish love for him, jerk!
Sakura carried out the normal check up procedure , but somewhere in the process took this as an opportunity to scrutinize his eyes.
"Uchiha, activate sharingan!" She breathed out fascinated, marveling at the beauty of the powerful kekkai genkai. How does it work? What provides the ability to conjure up this power? She studies his eyes more closely. Ruby stared back at her, a blood red. There are two types of two photoreceptor cells in a sheet of receptors at the back of the eye, rods and cones. Rods detect light levels and motion while only picking up black and white images whereas cones solely perceive color.
Restricted space in the retina so you can only increase the count of one if you reduce the other. Sharingan concentrates mostly on motion so the number of rods would be increased. That would make sense, except it would sacrifice his ability to see in color. As far as she knows, Uchiha isn't color blind. "Uchiha, can you see color?"
What a strange question… "Yes." He answers. Why did she ask that? When Sakura frowned and peered closer into his eyes, he understood. Sakura is studying my Sharingan. The thought came to him suddenly, Sakura happened to be oblivious to his discovery.
Sakura unknowingly was clutching the sides of his head to complete her thorough inspection. They were so close, they could kiss. Funny that this thought came to Sasuke rather than Sakura. Sakura was busy trying to figure out the anatomy of sharingan. She decided finally that is eyes are a fairly usual size, so it's not caused by a large retina.
Unexpectedly it clicked, the evident factor is extra pupils. Growing the number of pupils would increase the number of outer edges to be lined with rods as rods are common around the eye. It explains how Sharingan users monitors motion so well and still see color. The first pupil gets a better sense of motion while the second pupil is devoted to color. The circle holds the pupils together for complete focus but the red color is convened through blood seeping into the eyes from burst blood vessels.
She now understood the anatomy of Sharingan and how it worked. She was so satisfied, she thanked Sasuke who cocked a delicate eyebrow. "You're free to go. " She says and he redresses quickly. That could have been akward but Sakura was pleased with herself for grasping this opportunity. "One more thing Uchiha, please if possible can you ask for Sensei to come to my house, after your training session, of course-"
"Why?" Sasuke questions, a glare in his eyes.
"That is none of your business Uchiha, please just give him my message." Sasuke gives her a long hard look before giving a begrudged nod, Sakura smirks. Perfect.
