As they rush towards the guild, Mira and Lucy went to Porlusyica's house and Erza inform the search party that they had found Natsu, using telepathy. When they arrive at the guild, Erza slam the guild's door opened

"MASTER!!!" Erza scream and run towards the old geezer
"HEY, MAKE A WAY!!!" Gray shout as he, Wendy, Tanjirou and Nezuko rushed to the infirmary, leaving Zenitsu and Inosuke behind. Zenitsu jaw drop and Inosuke ignore all the stares and drag Zenitsu to the infirmary. While at the infirmary, Gray slam the door open and Tanjirou quickly put Natsu on one of the beds. His face clearly show he's in pain. Nezuko went to Natsu's side and grab his hand. She stroke Natsu's hand gently and softly hummed a lullaby that she once sang to her little siblings. She glance at Natsu's wound before look back at him. She bent closer to the pinkette and plant a kiss on his forehead

"There, there. Everything's is going to be alright" She whisper to him, "Onee-san is here" Nezuko run her fingers through Natsu's soft sakura hair. The pinkette seems to relaxed a bit at her warm hand. Nezuko smile a bit and continue to hum some lullabies

Tanjirou stand beside Nezuko and look at Natsu. He frown. Right now, Natsu really like his little brother especially after Natsu called him brother... The redhead sigh, and look at Gray and Wendy
"When will the healer arrive?"
"Maybe another few minutes. Don't worry"
"I see... By the way, my name is Kamado Tanjirou and this is my sister, Nezuko" He smile
"Gray Fullbuster and she's Wendy Marvell" Wendy smile a bit and walk closer to Natsu's bed
"You really care for Natsu-san" Nezuko nod
"Natsu is like my little brother..."
"I see. I also sometime look Natsu-san as my brother"

Both Nezuko and Wendy talk to each other. Gray just stand there silently watching the girls talk. He sigh and his bangs cover his eyes. Tanjirou glance at Gray. He can smell some guiltiness from the ice mage. Gray didn't notice that Tanjirou is staring at him. His mind just fill with guiltiness, especially after seeing Natsu shed his tears

It's all my fault

•••°°°•••

"So it's seems that the team is actually the Demon Slayers I requested for" Makarov close his eyes as Erza finished telling him everything. The remain search party had returned and they all surround their master. Levy look at him
"So, what now master?"
"How about we beat them up for hurting Salamander" Gajeel crack his fingers. Unnoticed by them, Zenitsu flinch
"I second that" Laxus cross his arms
"But I thought master request them to defeat the demon?" Lisanna look at the duo
"Lisanna's right. Besides one of them seems to care about Natsu, especially the demon girl" Erza cross her arms
"Hmm, there must be a reason why she care about Natsu" Freed look at Laxus, the lighting dragon slayer look back at him. They all look at Freed

Then, Porlusyica, Lucy and Mira slam the door open. The three of them rush to the infirmary, "I'll check on them" Erza excuse herself and jog to the infirmary. Makarov sigh, "You are all dismiss, also tell the demon slayers to see me in my office" Makarov sigh and walk to his office. The group of mages look at each other before look at the two remaining demon slayers. Levy walk to them, "The master want to see you in his office"

"But, what about Tanjirou and Nezuko?"
"Don't worry, we'll inform them later"
"Is Kitsu going to be alright?"
"He's Natsu" Levy smile. Zenitsu and Inosuke share look
"Come on, let me guide you to master's office"

The two follow Levy. As they walk pass the search party, they received glares from the iron and lighting dragon slayer while the remain mages are just stare at them. Lisanna look at her comrades, "Uh.. I will inform the other two" She walk towards the infirmary

Zenitsu shivers at the look the mages give them. He glanced at the infirmary's door, hoping for Tanjirou to show up

Tanjirou, we need you right now!!!!

•••°°°•••

"You're lucky that Wendy had manage to stop the bleeding or else he will die due to blood lost" The healer sigh

"Is he will be okay?" Tanjirou ask her. Porlusyica put her hand at Natsu's forehead. A small green magic circle appear beneath her palm
"He just have a slight fever, but he will be fine if he rest for a few hours"
"I see"
"Natsu had a fever?" Happy look at his partner
"Yes, please tell him that he shouldn't play in the rains or push himself towards his own limits. Don't think that a fire mage can't have fever or any illness. To my research, fire mages is the ones who actually really easy to catch a cold, especially dragon slayer" Porlusyica look at Natsu
"Why?" Mira ask
"It's because of the heat inside of them. Once they lose that heat, they easier to catch a cold or get terribly ill. As for fire dragon slayer, they need to make sure that their temperature normal. Their temperature will fall if they keep on pushing themselves to their limits, play in the rain for far too long or depressed"
"D-Depressed?"

"Yes, it's mean they already on their limits. It's dangerous for Natsu if he's depressed" Porlusyica stroke Natsu's head gently, "I'm worried if one day he will stop smiling and stop being himself. I cannot be so sure when he woke up, he will act like himself but instead his eyes will dulled and loss it's usual colors" Gray, Happy, Erza, Lucy and Tanjirou's eyes widen. Nezuko stare sadly at Natsu while Mira and Wendy close their mouth with their hands. Porlusyica sigh sadly, "I also afraid that he will start to blame himself for what happened around him. If we ignore it, he maybe will try to commit suicide"

"I'm not letting it happen" They look at the ice mage. Gray's eyes shadowed by his bangs as he grit his teeth. There's no way in hell he will let Natsu commit suicide again. He won't let it happen, "I will not let Natsu... Do it again..."
"Gray..."
"I just swear to Zeref and Mavis's names that I will help and protect Natsu... No matter what. I promise to Zeref that I will protect Natsu... I owe him a lot..." Gray tighten up his fist. Porlusyica smile a bit
"Even if you and this boy are rivals, you really care for him" A slight blush appear at the ice mage's cheeks
"W-Well, it's not like I totally hate him or whatever" Erza smile at him
"You love him right?"
"Uh..."

Tanjirou look at them. As he about to say something, Lisanna open the door
"Uh, master want to see the two demon slayers"
"Huh?" Gray raise his eyebrow
"Oh, I see. Come on, Nezuko. I guess he's our client" Tanjirou put his hand on Nezuko's shoulder
"Wait... You're demon slayers?!" Gray jaw drop
"Yes"
"What the hell?!"
"We're sent here to slay some demons in your area. I'm guessing that's why he requested for some demon slayers" Tanjirou smile
"I'm a demon slayer too!! Why gramps didn't tell me about this demon?!"
"Uh..." Mira sweat drop

"If you're here to screaming about this nonsense while your friend is resting, I'm suggesting you do it outside thi--"
"WHYY?!!!!"
"THAT'S IT!!! OUT!! OUT YOU PATHETIC HUMANS!!! DON'T BOTHER YOUR FRIEND ANYMORE!!!" Porlusyica kick everyone out, I mean it. She really kick everyone including the Kamado siblings
"W-Wait!!" Lucy stand up
"What?!"
"At least let me and Happy look after Natsu"
"Aye sir!!" Porlusyica stare at the two before sighing
"Fine" The two smile and thank the healer. Porlusyica look at the other, "And you will stay away from Natsu or else I will kill you" She glare at them. They shivers at the glare, including Erza and Mira. They nod. Lucy and Happy enter the infirmary while Porlusyica close the door

"Come on, Nezuko. Natsu will be okay" Tanjirou grab his sister's hand. Nezuko look at the infirmary door before nod and sigh
"Let's go..."
"So... Mind show us the way to your master's office?"
"Sure, just follow me" Lisanna smile
"Thank you"

"Come on, Gray. You need some rest" Erza look at Gray. The ice mage stare at the infirmary door before walk away

•••°°°•••

"Zewef-niiiiiiii!!!" Little Natsu ran to his brother with tears in his eyes. Zeref looked up from his book and immediately pulled Natsu to his embrace
"What's wrong little brother?"
"The-there's a scawy man twied to huwt me!!" He buried his face to Zeref's chest. The older Dragneel's eyes widened and he picked the boy up
"Shh, you're safe as long as Zewef-nii with you" Zeref whispered but the boy still sobbed. Zeref eyed his surrounding, in case there's someone watching them. He patted the boy's back, "There, there. Zewef-nii is here. Natsu?" The boy look at his eyes. Zeref smiled and wiped his tears
"Do you remember the man's face?" The pinkette nodded
"He uhh... Had scawy face... Wong blue hair... He had this weiwd mawking on his face... He's skin is bwown I think..."

Acnologia?

Zeref wanted to said the name, but he better not too. Zeref walked back to their home, with Natsu still in his arms. The pinkette laid his head on Zeref's shoulder
"Don't worry... Nii-chan will protect you no matter what" Zeref whispered

•••°°°•••

Slowly, Natsu open his eyes. He blink. He just dreamed one of his memories with Zeref again. He look around and immediately realize that he's at the infirmary. Natsu slowly get up, but a strike of pain coming from his stomach. Natsu look at his stomach. A bandage was neatly wrapped around his wound. He look around the infirmary. He was alone. He can't see Nezuko around or even Tanjirou. He sigh. He shouldn't keep on hoping the two will always by his side...

He sigh again. Bangs cover his left eye. Like Porlusyica said earlier, Natsu's eyes slowly loss it's color. Staring at the white infimary blanket. He just stuck in his thoughts, don't even notice that someone just open the door

"Natsu?" He slowly move his head, to see the person. Hoping it will be Tanjirou... But it's only Lucy and Happy look at him with glad expression
"Luce... Happy..."
"NATSU!!!" Happy fly to Natsu and buried his head to the pinkette's chest. Natsu smile a bit
"Heyya, buddy"
"You make me worried!!!"

A burden...

Unnoticed by Happy, Natsu narrow his eyes but he still smile, "Sorry..."
"Natsu..." He look up. The blondie is holding back her tears
"Luce..." Without a warning, Lucy hug him
"Idiot!! You just have to make me worry about you!!"

You keep on make people worry about you...

"I'm sorry..." Natsu barely whisper. Lucy pull herself from the hug and stare at Natsu's dull eyes. She frown. She keep on wonder why... Why Natsu still smiling while his eyes saying otherwise? Did he doesn't want them to worry about him? Her bangs cover her eyes
"No... I'm sorry..."
"Why?"
"Because I was being selfish... I keep on thinking about my feelings and never realized that you suffer more than me... But at least I didn't keep my hidden feeling to the guild... Natsu" She look at him as she noticed the way Natsu change his expression. But he firstly frown... Then he chuckled
"So, I really do make you guys worried..." He smile, "Sorry about that" He grin
"Nats--"
"By the way, where's Zenitsu, Inosuke, Nezuko-nee and Tanjirou-nii?"

"Huh?" The two stare at Natsu for a while. He just casually call his kidnappers by their names and heck... He just call Tanjirou and Nezuko as his older siblings but the truth is, Natsu is actually older than them
"Oh, they're still need to talk to the master, even though they had talked yesterday"
"Wait what? How long I've been out?"
"Not that long, just a day"
"So... Gramps knew about the whole 'kidnap' problem?!"
"Natsu... We need to tell the master... You were kidnapped by demon slayers"
"I don't care... If it's wasn't for the whole kidnap situation, I wouldn't met Nezuko-nee..."
"Natsu"
"No, Lucy. Don't 'Natsu' me!! You wouldn't understand!!"
"I would understand if you aren't keeping this depression stuff on by your own!!"
"So... You did notice... I wouldn't be surprised" He sarcastically said while rolling his eyes. Lucy's eyes twitch in anger
"Why are you so stupid Natsu?!!"
"Well thanks for reminding me of how stupid am I"
"I care about you!! I always open up to you... But why didn't you open up to me?!"
He chuckled darkly, "Maybe you would stop being my friend, Lucy"

Lucy's eyes widen. Tears begin to fall from her eyes, as she heard Natsu said her name... Not her nickname. Happy look both at Natsu and Lucy. He want to stop the two from fighting, but the situation was harder than he thought

"Now, are you done talking with me?"
"Natsu..."
"What? Oh so you're going to say that gramps will sent them away? Oh thank you very much. I was hoping for you to say it. I don't want to make them worry about me too... Let them worry about the demon that they need to kill. I'm not that worthy to be worry about" He sigh
"Natsu... I..."
"Now, I don't want to hear anything... I want to be alone. So get out..."
"Natsu, listen please"
"I say, GET OUT!!!" Lucy jumped. Natsu never raise his voice at her. Happy fly to Lucy's side. He was also shocked, he never see his partner like this
"I JUST SAID GET OUT!!!" Natsu took one of the pillows and sent it fly towards them, "GET OUT!!"
With a heavy sigh, Lucy walk out the infirmary, "Come on, Happy"
"Eh?"
"Natsu need some alone time"

She glance at Natsu, who ready to throw another pillow at them. Happy look at Natsu before nodding. As the two walk out the infirmary, tears begin to form in his eyes. He wipe his endless tears with his hands. A small whimper was heard but soon, he was sobbed. Ignoring the pain at his stomach, Natsu just cry and cry, releasing everything. While with Lucy and Happy, they heard him. All the cries and pain he had bare for years of living. They can hear the way Natsu sob and scream, it fill with regrets, pain and sorrow. Lucy lean at the door and she slide down. Hugging her knees, as she begin to cry softly. Happy sit beside her and look at his foots

Happy felt useless right now. He doesn't know what to do. He felt regrets for not notice Natsu's pain earlier

Natsu had throw everything around him. Completely ignore the pain, he buried his head into he's knees, still crying

You're broken... And you know I'm right, right~ Natsu Dragneel is nothing but a mistake, worthless, useless, burden and everything~

I...

Natsu's eyes widen. He was sitting on the bed with his legs are hanging from the bed. From beautiful olive eyes, it's slowly turning grey and dull eyes

"You... You're right..."

•••°°°°•••

I just had few writer's block and I hate it... So, sorry about the dark thought. I just, maybe I just recently had a small bad mood or something... Idk, but it's ok, I'm fine now. Besides the dark thought isn't actually Natsu's inner voice ヘ(￣ω￣ヘ)

Uwu, I wonder who was it? (~‾▿‾)~
