A/N: Hello again! This is my first attempt to write some sort of multi chapter story so let's see how it goes. Lately I've read many wonderful and incredible fanfics that I just got inspired to give it a try. All opinions and reviews are very welcome because they help me to improve so don't be afraid to tell me what you think!

Sakura was currently in her office at the hospital, taking small sips from her cup of tea, trying her best to calm a little and ignore the ever present foreboding that things might turn horrible for her that day.

"Everything is fine, they will arrive at any moment safe and sound" She repeated to herself like a mantra.

Naruto and Sasuke had become ANBU two years ago, and even when she wasn't happy with the idea, she respected their decisions. Don't get her wrong, this was mostly because Kakashi gave them missions difficult enough for their abilities but always something they could easily handle despite the reputation of ANBU missions, meaning there was no solo missions, not absurdly-impossible-to-do-without-dying missions and things of the sort, so she was fine with it...most of the time, and just because it was uncommon for them to get hurt.

In the present day everyone knew they were among the most powerful shinobi of all nations, if they were not the most powerful actually, so they were good, stupidly good at what they did, and it was rare to see them at the hospital for something more than chakra exhaustion when their missions got longer than expected or they took too many in a short time. Being who she was, she always chastised them for this but since it happened once every few months, she just let it pass.

Now the situation had changed: they were visiting the hospital more often and not just because they wanted to see her. In the last three months, they had been at the hospital 5 times, and that would be fine if it wasn't for the fact that's the total number of times they would usually go there, but in a whole year. These few times they have arrived considerably injured, not at the verge of death, but pretty serious when you considered it was them. Most of the time these visits were because of Sasuke, being that Naruto had the Kyubi healing most of the most severe injuries, but regardless of that, both were always in need of medical treatment.

Since this started happening, it was now usual for Sakura to be left feeling anxious and worried with every mission they took, fearing one of those times they would arrive too late for her to be able to do something or wouldn't arrive at all.

She pushed away those gloomy thoughts and began to work on her paperwork again. A few minutes into it and the sound of a voice in the speaker reached her ears.

"Haruno-san please report immediately to the emergency room".

Her chest tightened but she got up quickly from her desk and got out of her office. She wanted to run to the emergency room because it could be them, but she figured she needed to maintain her composure if she wasn't sure just yet. When she was mid way to it, a nurse reached her, panting slightly.

"Sakura-san, it's Naruto and Sasuke-".

Her heart stopped.

"Are they...?" She mumbled.

"No no, but they are not looking good and we don't know what's happening. We need your help" She said hurriedly.

At this, they both started running to the emergency room, while Sakura did her best to try to calm her trembling hands and heartbeat. Once they arrived, she saw many nurses trying to hold down Sasuke and Naruto, who were writhing, to their stretchers. As she walked to them, she took a good look at their appearances: they were bruised and had a few cuts here and there, on their bare chest they had a couple stab wounds which were bleeding profusely but nothing they couldn't fix, so why were they so concerned?.

"What's happening?" She asked putting on a pair of gloves.

Shizune was there, trying to grab a hold on Naruto but failing quite miserably. She looked at Sakura with a look of pure terror, and the later paled.

"I-I don't know, they arrived here on their own, pretty wounded but relatively well and talking" She explained. "But as soon as we started treating their injuries, they began to scream and writhe and..."

She stopped talking, trying to do something to Naruto but she didn't even know were to start. Her hands began to glow green again and hovered them above his chest, but as soon as she started pumping her chakra into the blond, he let out an ear piercing scream.

"Stop stop!" She said quickly.

She hurried there but halted when Sasuke screamed to her other side. She turned and saw another medic trying to heal his wounds with chakra. 'What the hell is happening?' She thought desperately and then something came to mind.

"Stop, everyone STOP" She shouted and everyone ceased what they were doing.

As soon as they stopped, the two men laying on the gurneys calmed down a little. 'Okay I need to think, to think of something and fast' she hurried herself. First, they arrived to the hospital on their own, wounded but without this horrible pain. 'Wait, wounded. Naruto has wounds and he's supposed to be-'

"Isn't Naruto healing himself?" She asked to no one in particular.

"When they arrived, Naruto-san said he wasn't healing and he didn't know why" A nurse beside the blond answered her.

'Okay, no good, he isn't healing. Keep thinking'. Second, as soon as they started treating their wounds with chakra they began to feel pain. 'Chakra...could it be possible...?' She questioned herself as she got closer to Sasuke with her hand glowing green.

"I'm sorry..." She whispered to him before pumping a little chakra into a wound on his chest.

He screamed in pain and began to writhe again harder. She stopped. 'Whatever this is, it reacts to foreign chakra' she mused in her head.

"Someone quickly take blood samples of both of them" She ordered the nurses.

"Why?" Shizune questioned.

"I think they were..." She trailed off.

Sakura's hand began to glow green again but she limited it to hover it above Sasuke, running a quick diagnosis. She noticed a strange substance spreading slowly not only through their veins but also contaminating their chakra, it was very subtle but it was there.

"Poisoned" She mumbled more to herself.

"What? Poisoned?" Shizune asked having hearing her and scowled. "But they don't show any signs".

"It's a small quantity but it's there...still, you're right, they don't show any signs and it's unlikely for it to be causing this but-" She shut her mouth as a thought came in.

She went to Naruto now, her hands glowing green and hovering them above the now unconscious man. She then looked at the medic in front of her.

"Shizune, pump a little chakra into Naruto, but just a little and stop if I say so please".

Shizune hesitated. "Okay".

She did as she was told and as soon as she began pumping her chakra into Naruto, he began to writhe and scream just like Sasuke before. While this happened, Sakura felt how the small amount of the strange substance that was in Naruto's bloodstream as well as mixing with his chakra, quickly augmented its quantity when it made contact with the foreign chakra, also spreading faster through his veins and chakra system.

"Stop!" She nearly yelled at the black haired woman and she did so. "This is-this is bad".

"Did you figure it out? What is it?" Shizune questioned her worriedly.

"I've never seen something like this before. They were poisoned with something that reacts to foreign chakra, that's why they were fine when they arrived here, and every time we try to heal them with our chakras, we just duplicate the amount and speed of the poison, it also seems to have a dual effect because it's not only damaging their body but making their own chakra toxic" She said stunned by her discovery, giving a few steps back. "Finally, I'm sure they were given some chakra suppressant so Naruto couldn't heal and they both would be weak enough to get the poison into them".

"It could have been through any of these stab wounds and cuts. It's not the first time someone poison their weapons" Shizune said clearly angry at her own statement.

"That's most likely" Sakura said absently, still thinking about what to do.

"But what do we do? If what you are saying it's true then we will kill them if we heal them with our chakra or try to extract the poison, and if we don't, they will die anyway when the poison reaches their hearts" The black haired medic said seriously.

"I-I'm not sure.." She stuttered, terrified.

Shizune and the other medic treating Sasuke began to scan both men. After a moment, she looked at Sakura.

"Sakura, we don't have much time. The poison will reach their hearts in matter of minutes and they are beginning to show signs of poisoning".

Sakura reached to Naruto and then went to Sasuke. Both of them were burning with fever and had a thin layer of sweat covering their body, their breathing was fast and shallow and she just knew they didn't have much time. She needed to do something and fast. She ran her fingers through her hair, thinking of something, anything, when thank Kami an idea enlightened her.

"It's risky" She mumbled looking at her boys.

"What? What did you think?" Shizune asked, desperation lingering in her voice.

"I can use my chakra to directly eliminate the poison from their body" She explained without looking at her.

"But won't that only accelerate the process of spreading? Because you will use your chakra on them" Shizune asked confused.

"Yes I will but instead of just making it circulate to get the poison out, I will use it to basically burn it out instantly on their bloodstream and chakra system. If I do it fast enough and with the right amount of intensity, I think I can pull this off but..it will hurt them an-and I'm not sure it will work" She said looking at Shizune with trembling hands.

The black haired woman seemed to consider it for a moment, then she looked at Sakura with determination.

"It's the best shot we have, we don't have any other option and it's best to try something rather than doing nothing".

"Okay" Sakura nodded to herself.

The pink haired medic positioned herself on Naruto's side and placed both hands above a stab wound on his chest. She took a deep breath. 'Please kami, let it work, I beg you' she pleaded silently and then bumped all the chakra she was able to gather as fast as she could. Naruto began to scream and writhe against her but she stayed glued to her task. Four nurses had to hold onto each of Naruto's limbs to keep him for hitting Sakura.

After what felt like a year but in reality was only a minute, Naruto went limp and she felt the panic creeping up her throat. 'I killed him' she thought the worse as she pulled her hands away from him and took a step back, afraid of checking him up. Shizune on his other side, hurried to feel his pulse and scan him. When Sakura was about to lose it, she spoke.

"He's fine" She smiled at the girl, trying to soothe her. "The poison did a number on his system and he needs blood but there's no poison in him anymore, we can work on him now".

"Sakura-san! Sasuke-san he's-" A nurse called her.

'Oh kami, Sasuke-kun!' She thought, hurrying to his side. He was pale and his breathing as well as his heartbeat was irregular. The poison was reaching his heart. She had to hurry.

"Hold him tight" She ordered to the nurses.

She was tired, doing this on Naruto was more exhausting than she initially thought but she didn't care, this was Sasuke, her Sasuke and like hell she would just let him die. She placed both hands on a wound on his chest and let out all the chakra she had left in a massive torrent. Sasuke's screams and writhing made her wince but she stayed put, and after a minute, he went limp. She saw a medic checking his pulse and scanning him.

"He's fine Sakura-san!" The medic said to her happily but she barely listened.

Her world was spinning mercilessly and soon the ceiling became the floor when her eyes went to the back of her head and she fainted, summing herself in pitch black.

When consciousness came back to her, she sat up startled.

"Sasuke, Naruto!" She called them.

She felt a hand on her chest, pushing her again to lay down on...a bed? No, that wasn't a bed, it was gurney.

'Oh'.

"I think you just figured what happened right?" A feminine voice said to her side.

"Shishou" Sakura said, turning her head to the blond medic.

"What you did was totally reckless, you could have killed them, not to mention you could have died too by depleting your chakra like that" She chastised the young girl. "But still...you saved them and I'm not sure anyone else could have pulled that off".

"I had to Shishou, you know I couldn't just let them die, I love them too much" She said closing her eyes.

"I know that, Sakura, and I truly hope that doesn't kill you one day" She shook her head at her former apprentice.

"How are they?" Sakura asked worriedly.

"They are actually waiting for you" Tsunade informed her.

"Really? But I thought-" She said frowning.

"Shizune told me that after you eradicated the poison from their bodies, that allowed them to easily use their chakra to work on them and heal all the wounds and damage the poison caused, something that took for around an hour" Tsunade explained to her.

"Oh, okay" She said relieved.

"They are good as new and as you may guess, they are refusing to leave without seeing you" The blond rolled her eyes.

"Thank you Shishou" She smiled, and then frowned as a thought came. "Did Shizune tell you about the poison?".

"Yes, and just like you, I never saw something like that before. We'll have to analyze it and see if we can develop an antidote" Tsunade pursed her lips in clear concern.

"I'll do it, that thing nearly killed them and I'm not going to risk for it to happen a second time" Sakura said, sitting again.

"Very well, you're in charge of that then" Tsunade said getting up from her chair.

"Hai, Tsunade-sama" Sakura nodded.

"I'll leave you to them. Take care Sakura" She said before disappearing through the door.

She had just managed to get up from the gurney and dust off her clothes, when someone engulfed her in a tight hug.

"Sakura-chan! Are you okay?" Naruto asked worriedly, his face buried in her hair.

Sakura giggled. "Asks the one who got poisoned and nearly died a few hours ago".

She pulled away and saw her two boys standing in front of her, very much alive. She felt a complete relief wash over her. They were wearing white hospital shirts and the bottom part of their uniform, which was still somewhat dirty and bloodied, confirming what Tsunade told her about them refusing to leave before getting to see her. She shook her head and hugged them both.

"You scared me to death, I thought for a moment I had lost you both" She admitted, hugging them tighter before pulling away.

"They told us what you did. That was stupid" Sasuke said flatly but Sakura could see the hint of fret he felt.

"Is that your way of saying you were worried Sasuke-kun?" She teased him.

Sasuke rolled his eyes. "I'm serious Sakura, you could've died".

"If I didn't do anything, you could've died" She retorted crossing her arms.

They both glared at each other in a silent battle. Then she sighed, looking away.

"I don't care, you both know I won't just let you die so you'll have to live with that" She stated stubbornly.

"Annoying" Sasuke mumbled under his breath and turned away.

Sakura just rolled her eyes and went to hug her blond boy again. He enveloped her with his arms instantly.

"How on earth did you two managed to get poisoned?" She asked, her voice a little muffled because of his shirt.

"We were around an hour away from the village when a group ambushed us. I think they studied us for a while because they were familiar with our fighting style so we couldn't get rid of them fast enough" Sasuke said looking at her and Naruto.

She pulled away from Naruto. "But how did they get so close to you to inject you with the chakra suppressant?".

"They didn't, they threw senbons at us" Naruto scrunched his nose. "At least that's how I think it happened because we couldn't use our chakra after that".

"And then I'm guessing they tired you off enough to cut you with the poisoned blades..." She said and both nodded at her. "Did you get to see who they were?".

"They were common missing-nin, nothing out of the ordinary" Sasuke said dismissively.

"That poison, the chakra suppressant and the fact they knew how you both fight, is the contrary of ordinary" She quirked an eyebrow. "But I guess they're just getting better. Either way, you'll need to be more careful from now on".

"We're always careful Sakura-chan" Naruto gave her a shit eating grin.

"Sure, and today is the very proof of that right?" She asked sarcastically.

"That doesn't count!" Naruto pouted.

Sakura sighed. "I'm being serious here guys, you need to be more careful and you know why".

"Hn".

"No, don't give me any 'hns' Sasuke, you know what I mean" She said glaring at the Uchiha.

"No" He deadpanned.

"You have been in this hospital 6 times counting today during the last 3 months" She stated. "You had never got this injured before in such a short time".

"It had to happen at some point Sakura-chan, besides, now we're having so much more fun with opponents who can actually give us a fight" Naruto joked.

"Naruto..." She trailed off, irritated by the bad sense of humor.

"We'll be alright Sakura, you know we are capable" Sasuke said getting closer to her.

"I know! I just..." Sakura shook her head and stared at her feet. "Can you both do something for me?".

"What?" Sasuke inquired.

She raised her head to look at both. "Would you come and see me after every mission? Just so I know you're okay and arrived well".

"But we're always okay and we usually go and see you some time later after we arrive" Naruto scratched the back of his neck.

"It's not the same. I want you to come to me just after you report to Kakashi" She fidgeted, giving them big puppy eyes. "Please?".

Sasuke rolled his eyes and Naruto sighed. 'Damn her' they thought. They just couldn't say no to her.

"Fine" Sasuke huffed.

"Alright Sakura-chan" Naruto consented.

"Love you both" She jumped to them and hugged them again. "Come on, let's go and eat something".

She pulled away and began to walk out of the room.

"Can we go to Ichiraku??" Naruto asked, following her close.

"Idiots" Sasuke muttered.

He shook his head and stood there for a second before trailing after his two best friends.
