Ok before we start the story, I just want to say that this story fulling originate and belongs to koregrace00. I have asked permission if I can rewrite their story and they said yes as well as I will credit them for the inspiration for this story. 
I absolutely love the story they created and I wish to read it again however, it was deleted and I didn't read the chapter of the reason why it was deleted because it was deleted before I can read it. So please don't attack me because this whole idea belongs to them fully and I'm just recreating this in my version adding AE3083's friends and U-1146's friends. Also I will be referring to red blood cells friends using their first letters and the white blood cells friends as their last two numbers because their names are too long and I can't remember their full name permanently.
I will say it again, THIS STORY FULLY BELONGS TO  koregrace00 PLEASE DO NOT ATTACK ME SINCE I HAVE CREDITED THE PERSON ALREADY, ASKED PERMISSION AND I HAVE ADDING THINGS TO THE STORY AS MY IDEAS AND TO MAKE IT NOT EXACTLY AS THE PERSON STORY.
Ok since we got that out of the way, let's start this chapter.

' oh no, where am I now' thought AE. This is the third time she got lost today and to make matters worse, her kouhai, NT4201 is with her.

After the hemorrhagic shock, NT started respecting her senpai despite her not being able to navigate the body well however, NT admired her senpai and her dedication.

" senpai, we should go over there since we passed this area before" said her kouhai. AE's eyes brighten and nodded.

" great work kouhai-chan" said AE as they started walking.

On the way, the saw several other red blood cells delivering oxygen or nutrients to normal cells in the area. There were even some white blood cells patrolling the area.

" Sekkekkyu-san?" said a voice behind the pair. They turned around and saw U-1146 and U-4989 behind them as 46 smiled at her while 89 waved at the pair.

" oh Hakkakkyu-san it's good to see you today? are you patrolling this area?" asked AE

" yeah are you and your kouhai making your delivery here?" asked 46.

" yeah I kinda got lost... he he" said AE as her face turned red due to embarrassment.

" it's ok, I can help you both if you want" said 46

" yeah that sounds great!"

" ahem" said NT. Their attention was then moved towards to her. NT knows who the white blood cell that her senpai would always hang out with but only that white blood cells name she can remember and know what not his friend who stood next to him.

" oh yeah, sorry kouhai-chan, hey 46, this is my kouhai" introduced AE to her other white blood cell friend.

" it's nice to meet you, I'm U-4989, you can call me white blood cell or 89 if you want"

" I'm NT4201" she said as her voice sounds dull as she introduced herself to the other white blood cell. " senpai, let's just deliver this oxygen first, we're already an hour late"

" oh yeah sorry!" said AE

" we can help you if you want" said 46

" if it's not too much trouble" said AE.

The four cells walked together to their destination. 46 and AE started talking while walking as AE pushed her cart with the box of oxygen while 89 was happily talking to AE's kouhai while she either seem to ignore or to just nod and not responding.

" I just hope there isn't any pathogen here. it would be such a hassle right?" said 89 to NT. NT just nodded while carrying the box of oxygen and she kept on walking.

" senpai, I need to make this turn since my delivery is on this path here, I think your delivery is the opposite of mine" said NT

" oh yeah it is, see you kouhai-chan" said AE as she waved at NT while she just nodded and gave her a small smile as they part ways.

AE and 46 keep on walking to her destination while talking.

" your kouhai seems to be a bit distant, did something happen?" asked 46

" oh just now? Um... no I don't think so" said AE while putting her right index and thumb on her chin thinking.

" .... I remember when I first met her she said that white blood cells are a bit violent according to nature" said 46. He didn't really held a grudge against red blood cells kouhai since he and the other immune cells would always get comments like they are scary, violent and some even weird. He got used to it after a while but he was just surprise and glad that at least AE isn't scared of him and is still grateful of it.

" oh yea, I remember, I'm really sorry about that. are you still mad about that?" concerned AE

" no, us immune cells get that almost everyday, it's fine, but I'm just thinking what she would say to 89 since he's a bit sensitive and emotional"

" oh yeah he is" said AE as she gave a small chuckle, she still remembered the time where 89 cried in front of her after worrying about 46 and complimenting their work.

" well this is your stop, see you later I guess" said 46.

" oh yeah, thank you Hakkekkyu-san, see you later" said AE as she waved him off and 46 just smiled and went into one of the ducts and to another place. AE knocked on the door as a normal cell opened it. " here's your daily oxygen delivery, please stamp here" she handed him a slip as he took out a stamp.

" your at least an hour late" said the cell after he stamped the slip and took the box of oxygen. " aren't you red blood cells supposed to be on time for their delivery?"

" oh uh... I kinda got lost" said AE with her face turning a bit red.

The normal cell didn't say anything further before shutting the door in her face.

" have a nice day..." said AE quietly before walking away feeling sad that she delivered her oxygen late to the cell.

Meanwhile with NT and 89, 89 keeps on rambling about his job while NT didn't really respond to him.

" I thought I was gonna die after getting sucked into the wound, luckily I held onto something. Thank God" said 89.

" do you always talk this much?" asked NT as this is the first time she finally spoke after 89 keeps on rambling and NT either passively listening or just nodding along.

89 was a bit taken aback since NT was just walking next to him and keeping quiet and even he doesn't know if she was listening but just assumed because she was just nodding.

" huh? Since you didn't really speak much I assume that you didn't really want to talk, plus if we just walk in silence, it would be even more awkward right? Plus the red blood cells around might think it's a bit suspicious that a while blood cell like me is walking around with you" said 89.

NT didn't want to admit it but he is right, walking in silence isn't gonna be much better much less then walk with an immune cell since red blood cells walking pass them were already glancing at their direction. And he does seem like a nice guy and is a friend of her senpai.

" yeah I guess...." said NT quietly. She finally reached her destination as she knocked on the door and a cell opened it and stamped the slip and took the oxygen box from her. She turned around and still seeing the white blood cell but he looks upset.

" are you scared of me?" asked 89.

This time, NT was the one taken aback. She didn't mean to make him upset nor give him the impression that she was scared of him.

" n-no, it's just that, your an immune cell and I'm not..." NT thinks a bit more before giving an answer to make him feel a bit better. " it's just, I was taught that immune cells were a bit violent when facing a bacteria. however, because of my senpai and your white blood cell friend, I wasn't scared anymore and... thank you for taking care and protecting us from pathogen in this body"

NT looked up to him as her eyes widen seeing 89 crying and then hugging her.

" thank you kouhai-chan!" said 89. NT just gave him three pats on the back.

" just call me NT or red blood cell"

Later in the day, AE and NT was summoned by AE's senpai, AA5100 and ME0808 who was the transfusion red blood cell when the hemorrhagic happen as they were there to save the body.

" AE, you and your kouhai was late to deliver the oxygen today" said AA.

" I know but please don't blame kouhai-chan, I was the one that got us lost so please don't get mad at her" begged AE as she doesn't want her kouhai to get into trouble because of her and to at least get mad at her then her kouhai.

ME just sighed. Despite AE being clumsy, ME does care about her since she is the first red blood cell that greeted her (even though it was a mistake and AE was saying to her kouhai instead of her but ME still appreciated it) and she heard about her antics from her co-workers and from her senpai.

" *sigh* the other red blood cells was thinking of punishing you for your late delivery and most of them agreed" said ME as she sees AE's face falls into sadness " however, me and your senpai have talked to the other red blood cell and agreed that me and your senpai along side your kouhai to help you with the punishment" AE's face then lightens.

" the punishment is that you will go around the body and memorize every path and blood vessels using the map and me, ME and your kouhai will monitor you incase you need help, this punishment will be going on for 1 week starting today" said AA.

AE felt bitter sweet, despite the punishment, at least she, her senpai, her kouhai and ME is going to be with her the whole time but she felt a bit bad that they have to take time off their delivery.

" thanks, I'm really sorry about this and I'm sorry if this is changing your post" said AE.

" it's ok, we just want you to do your deliveries" said ME.

AE took out the map from her red bag and they started walking around as AE stated writing down notes and trying to memorize the blood vessels.

AE was so distracted with looking around and writing notes that she didn't know where she was going and the calls of her name was muffled as she suddenly bumped into someone as she fell down.

" ah! I'm so sorry! Please forgive me!" said AE.

" sekkekkyu-san? are you ok?" asked a familiar voice. AE looked up and saw 46 offering her hand as she accepted it and he helped her get up.

" Hakkekkyu-san, I'm really sorry, I didn't mean to bump into you" said AE feeling embarrassed.

" It's ok, it's fine, I am currently on my break" said 46.

" senpai/kouhai/AE!" shouted NT, AA and ME as they caught up to her. AE and 46 looked back and saw them running towards them.

AE was always told by everyone even AA that she is a fast runner even walker that even NT have trouble keeping up with her.

" oh sorry that I walked off" said AE apologizing to them.

" it's ok. oh hey your the white blood cell that's friends with her right?" asked AA as her attention went to the white blood cell.

" yeah, do you all have a delivery here? I don't see any oxygen boxes nor carbon waste and no nutrients" asked 46.

" oh uh... I'm currently being put in punishment because of my late delivery so we're just walking around and they are helping me memorize the area and getting familiar" said AE.

" oh does that mean I won't see you on your deliveries often now?" asked 46 feeling a bit sad since he enjoyed seeing her around and accompanying her even listening to her stories.

" hey 46 have you got your tea yet?" asked a white blood cell behind 46.

The red blood cells attention was then pushed to the three white blood cells. One of them is U-4989 who was with NT earlier during her delivery, the other one has a straight symmetrical hair cut as they read U-2048 as AE remembered him from the stomach during the parasite invasion as well as meeting him with 89. The other white blood cell had his eyes covered with his long bangs as the number was U-2626 on his hat as AE remembers him from the attack as the Macrophage ended up saving them as she handing him a tissue to wipe the cytoplasm from the pathogen they fought.

" oh hey 89, 26 and 48, how are all of you?" asked AE.

" doing great thank you for asking" said 26, when he met AE when she gave him the tissue to wipe the cytoplasm he was surprise but appreciated the offer.

" thanks for asking red blood cell- san, I'm doing well and your kouhai is really nice" said 89, AE is the first and only non-immune cell other then the Platelet's who cares and appreciated their job and is concern of them as he really cares about her.

" doing well AE, don't fall in love with me since it may distract you from your job and I don't want to distract you more then you already are" said 48. since meeting AE in the stomach, he has been really nice to her and even meeting her again with 89. he knows that AE will easily get flustered when he flirts with her however, this caused 46 to feel a certain discomfort. " are you and your friends here to make a delivery? I don't see anything on someone cute like you" he flirted with her again as AE started blushing and stammering.

" u-uh, w-we-well, y-you see-" AE was about to answer before 46 interrupted her.

" she's currently going around and memorizing the blood vessels to get familiar with her senpai, kouhai and ME" said 46.

" oh really? well I hope you can find your way" said 26.

" you haven't introduce us to your friend yet princess" said 48 as he flirted with her yet again.

" oh yeah, this is my senpai, AA5100"

" hi"

" this is my kouhai, Nt4201"

NT simply nodded to them.

" and this is the transfusion red blood cell during the hemorrhagic shock, ME0808"

" it's nice to meet you"

" nice to meet you too mademoiselle" said 48 as he took ME's right hand and kissed the back of her hand as ME started to furiously blush. After that, she took her hand back and looked away refusing to let him see her blush.

" it's nice to meet you red blood cell" said 26 to AA

" same to you white blood cell"

" seems like we meet again kouhai-chan" said 89.

NT only nodded before turning her attention to the group.

" not to bother all of you on your conversation but I think it's time for senpai to continue with her journey of the body" said NT reminding them.

This helped snapped them back to their senses.

" oh yeah I almost forgot, see you Hakkekkyu-san" said AE as she and her friends waved them off. 46 waved back as they disappear into the crowd.

" hey 46, why don't you just tell her you like her already? if you keep this up, I'll really flirt with her until she faints" said 48.

" if you do that I'll put you into either an early apoptosis or phagocyte you" said 46.

" seems like someone is a bit jealous. scratch that, a lot jealous" said 89

" he didn't denied the fact he will flirt with her though" said 26.

46 simply rolled his eyes as they walked away with his friend still joking about him and that red blood cell.

Meanwhile with the red blood cell, they started to wonder off to one of the foot as the area around them was really deserted and the buildings were old and abandoned with barely any cells around.

" this place seems a bit creppy, we should head back since there isn't much around here and there is barely anyone" said ME.

"yeah your right" said AA.

They were about to leave before they saw four figures wearing similar clothing to the white blood cells however they were all black.

" hey is that, Hakkekyu-san?" said AE as she pointed at the four figures.

" they do look similar" said NT. They started approaching them as they tapped on their shoulder.

" um... excuse me? Hakkekkyu-san?" said AE.

They figures turned around and their eye's widen.

The figures look a lot like the white blood cells they met just now but they have black hair instead of white and their clothing was all black and their hat had no name whatsoever.

" who are you and what do you want?" said one of them who looks similar to 46.

Yep gonna leave it here for a moment. This took 3 hours to do so let me rest for a bit. hope you like the story so far. Bye!
