Chapter 1: My Good Looking Boy

Summary:

Dazai goes to school and finds out there’s a new kid and he also hangs out with his friends. Let me know if I spelled anything wrong btw thanks for reading<3

Chapter Text

Dazai opened his eyes feeling the dread of life seeping into his soul. “Shit,” he mumbled realizing he has to get ready for the prison that is school. Running a bony hand through his oily brown hair. He looked at his alarm clock which he never actually set, to see it read 6:45 AM. Nevertheless he slipped on his dark blue uniform. He was forever grateful for the long sleeved shirts although the fabric was itchy. The black tie always caused him some trouble and the pants were a bit baggy for his liking but it could be worse. Stretching his hand out he pulled his plastic toothbrush and put cherry flavored toothpaste on it. He barely brush his teeth anymore even though he clearly should especially since he got braces. Returning to his main room Dazai decided to take out his sketchbook from underneath his bed, filling in a blank page with random drawings. He thought about drawing his sickly room which was extraordinary messy with dirty clothes scattered around. No matter how many times his step mother yelled he couldn’t bring himself to clean it. So he would make up a nice clean small room to draw. Doing this for quite some time he heard he’s sister knocking on his door.


“Osamu open the doorrrrr,” Elise, his half blood sister, beamed making sure to drag out the last syllable.

 

“Elise quit that noise,” He heard his step mother say softly.

 

“Fine, I’m sorry mom.” He knew his step mother had favorites, it hurt but he knew why. Dazai knows if he done something like that screaming would have met him. The door opened showing Elise’s long blonde hair in the dark frame of the door.

 

“I hope you haven’t forgotten to take me to school Osamu.” Elise frowned seeing that he still barely looked ready in her finest opinion.

 

“Elise,” he said as he pointed to the Alarm Clock which now read 8:15, “You still have at least five minutes before we have to leave, also we go to the same school now remember.” Dazai knows he not allowed to drive with other people yet legally but his parents don’t give two shits unless he’s caught. Also with Elise now being a freshman in the same school as him, driving to school has been a nightmare.

 

“Just make sure I’m not late okay,” she huffed as if she has a reputation to keep up for not being late, Dazai rolled his eyes.

 

“I might just make you late on purpose now Elise~chan,” he knew this would piss her off, just saying her name as annoyingly as possible. Humans were always so essay to rile up.

 

“Kill your self."

 

“With pleasure,” he chuckled as she slammed the door. There mother must have left during there interaction he thought as he opened back up the door slightly. Dazai reached for his bag, phone, and keys as he made his way down the stairs. He found Elise waiting by the front door, not even making eye contact, she must be giving him the silent treatment let’s see how long this lasts he thought. He opened the door walking down towards his car, Elise raced behind him. Inside the car Elise instinctively reached for his phone opening Spotify, after looking for a while she choses Lana Del Ray and puts it on shuffle. Dazai doesn’t mind her music taste, not that he would ever tell her that. Once they arrive she slips out of the car running off to her friends. After parking he walked towards his first period, English. The English room was almost filled with students all talking and laughing. Dazai would occasionally eavesdrop on the popular girls who sat in the back with him only separated by a desk.

 

“Did you hear we’re getting a new student today?” A blonde girl whispered he didn’t care to catch the name of the new student but continued listening.

 

“We are? Wait is he hot? What’s he look like?” another girl basically yelled with excitement. He realized the conversation wouldn’t give him any information and just waited for class to start. This class was one of the subjects that he liked mostly just because of the teacher, Sakunosuke Oda or as his students would say Odasaku. Odasaku started class with no sign of a new student yet, Dazai was intrigued to see the new kid for a reason he didn’t quite understand. Turns out new kid was late and knocked 5 minutes after the bell rang. Dazai looked towards the door to see an alluring boy with fiery ginger hair that was pulled back into a small pony tail. His eyes were a clear blue but his right one looked as though it was covering something up maybe contacts he thought. He had two piercings per ear with an eyebrow piercing just above his left eye and looking further down Dazai could see that he was wearing black gloves. As much as Dazai would hate to admit he was appealing to look at, since coming to this conclusion, he had the urge to draw this boy. He could also hear the group of girls from earlier basically squealing like pigs silently, of course.

 

“I’m sorry I was late, I had to meet with Ango.” The ginger unapologetically stated but the way the boy talked was smoky and appealing to the hears.

 

“It’s okay, I’m guessing you’re Nakahara Chuuya?” Odasaku didn’t seem surprised with him being late as the boy handed in a late slip.

 

“Um yeah, just Chuuya is fine though, you’re Mr. Odasaku right?”

 

“Precisely, now that we have that clear up take a seat by the boy in that back with brunette hair.” Dazai knew it was coming since it was the only empty seat left but he couldn’t also help feel intrigued by Chuuya. As Chuuya sat down next to him, Dazai couldn’t help noticing the way Chuuya’s faint freckles brushed along his nose and cheeks. He felt the need to try and count each individual one. He was so focused on counting the freckles that he didn’t realize Odasaku had started the lesson. He saw Chuuya bend over to his bag and pulled out a black note book. Dazai quickly copied and tried to focus on what Oda was saying in case he got called on.

 

“As I was saying we’re going to get into groups of pairs for this project, I will give you some time now to move your desk by your partner,” Oda instructed while Dazai had no clue what they’d been talking about for the past 20~ minutes. He’s going to need to find a person to partner up with. Oda actually came up to his desk after seeing him not move for sometime.

 

“Dazai are you going to partner up?” Oda asked looking around for potential candidates.

 

“Of course I’m just thinking about who would be best for this project.” He had no slightest hint on what this topic was on but he was sure he’ll figure it out.

 

“How about your partner up with Chuuya? you have seemed to In joy staring at him after all.” Odasaku smiled as he began looking at Chuuya who had been going around looking for a partner. Dazai felt the slightest hint of embarrassment at being called out but hide it with a smirk.

 

“Chuuya can you come here for a minute?” Odasaku waved him over. Chuuya moved across the sea of people toward them. Dazai saw the Chuuyas confidence raidate around the room, each step he took made Dazais heart rate spike.

 

“Mr. Oda what can I help with?” Chuuya asked politely while staring daggers into Dazai’s soul.

 

“Would you mind being Dazai’s partner for this project?” Dazai’s face sifted into horror at the realization he now looked like a little wimpy kid who was scared of talking to people. He soon turned back into, His normal self sending a toothy grin towards Chuuya. Chuuya’s eye twitch for a brief moment before turning towards Oda.

 

“I wouldn’t mind a bit Oda.” Chuuya said like he did in fact care a lot. Dazai already made up a thousand excuses for starring at him earlier. He moved his desk right next to Chuuya’s and waited for Oda to start.

 

“Alright, seems like you all have a partner so I want you guys to dived up the work evenly, begin.” Dazai was hoping someone would ask a question about the project to give him more information but that did indeed not happen.

 

“So Which book do you want to read?” Chuuya asked clearly slightly annoyed.

 

“I didn’t catch what the book criteria had to meet,” Dazai hoped he played that off while.

 

“The book has to be at least 400 pages long and an autobiography,” Chuuya sighted off his notes.

 

“What about Jane Eyre by Charlotte Brontë?” He blurted out. This was in fact the only book Dazai could think of. He’s never read the book but has briefly skipped through the translated version of it in the library.

 

“Sure, I guess we’re going to make a trip to the library, also do you want to read the book all together or alternatively?”

 

“I would prefer together so we can both have a equal amount of understanding,"
they walked over to Odasaku to ask about going to the library.

 

“Oda-san could me and Chuuya-kun go to the library?” He said in a singsong tune.

 

“Sure, take a pass also take this opportunity to show Chuuya around.” Odasaku smiled softly at Chuuya.

 

“Okay, come on Chuuya,” Dazai sipped the pass into his pocket as he was then planing on booking it to the library.

 

“Wait, what the fuck!” Chuuya yelp as Dazai ran while dragging him along. The last part of his sentence faded out of the classroom. They stopped a few feet away from the library.

 

“What the hell was that for you slimy bastard!” Chuuya shrieked, “Do you have no common decency?!?” Oh he was so pissed Dazai thought with a grin plastered on his face.

 

Dazai gasped “I didn’t think you knew such hurtful words dear Chuuya!” He said in fake shock.

 

“Th- Do you think im a fucking chid or some shit?!” Chuuya sounded like he was going to pop a blood vessel. Dazai made note of his reactions.

 

“Yeah, I mean who wouldn’t with that height,” Dazai looking him up and down.

 

“You’re not even that much taller waste of bandages,” his gloved finger pointed out to touch Dazai’s chest. Dazai was a bit surprised with the action and the nickname. Wast of bandages, huh that was a new one.

 

“Keep telling yourself that.” He looked down at Chuuya’s finger and moved away slightly.

 

“Fuck off.” He started to storm away until he most likely realized they have a project to work on. He watched as Chuuya turned around and stormed towards the library.

 

“Shhhh where going into the library Chuuya,” Dazai walked in seeing a few other classmates looking for books. He walked towards the autobiography section with Chuuya close by. Looking in the section he could see there was only two copies of the book left. Coincidentally they both reached for the same one, Chuuya’s warm gloved hands brushed against his icy skin making a shiver run down his spine. Quickly he reached back letting Chuuya take that one. After they checked out, Dazai took it upon himself to show Chuuya his class so he wouldn’t be lost. Which was weirdly nice of him.

 

“Give me your class schedule,” he demanded.

 

“Why would I do that idiot?” Chuuya looked confused but he started to reach for his schedule anyway.

 

“I’m showing your classes to you silly!” Dazai showed a bright smile with his braces on full display.

 

“Don’t pull anything fuckface,” Chuuya cusses a lot, Dazai would make note of his habits. He glanced over Chuuya’s schedule, for the most part they had the same classes except for PE and electives. The tour was quite quick since they didn’t have to go that far, but this was an opportunity for Dazai.

 

“So do you know any people here yet?” He asked when they started to walk back towards the classroom.

 

“Yeah, why? What’s it to you?”

 

“Nothing I guess, it’s not surprising especially since you have such an amazing personality,” he said really sarcastically. Chuuya rolled his eyes.

 

“I joined a band when I first came to Yokohama and found out they go this scho-“ he was then cut off by Dazai.

 

“Oh so you’re the new lead singer for Gins band.” he knew Gin well since tutoring her brother.

 

“How did you know that?”

 

“Gin mentioned getting a new lead singer, I didn’t think they would in-roll here though.” they walked in silence for a bit before Chuuya spoke again.

 

"Dazai how do you know Gin?"

 

"I tutor her bother in math but were not close," Dazai stoped in front of the door knocking lightly. One of the girls from earlier opened the door blushing hard when she saw Chuuya behind him. Dazai went to give the slip back to Oda as Chuuya made his way to the desks. They moved the desks back to normal as the bell rang they sperated going to there 2 periods. Dazai made his way to History and sat down in the back. His History teacher, Fukuzawa was another one of his favorites. Fukuzawa's son Ranpo was one of Dazais friends who happened to be in the same period. Ranpo took a sit next to him with Yosano by his side. Ranpo propped his feet on to his desk with a lollipop in his mouth. Yosano was first to speak, "Did any of you guys see the new kid yet?" she said with her face turned towards the both of them.

 

"No, but I know Dazai had first period with him." Ranpo faced Dazai giving him a wink.

 

"Oh?" she said noticing the wink, "Dazai what did you think of him?" Yosano loved hearing about any new gossip.

 

"Well he is good looking but hella short and is obviously obsessed with me of course," Dazai grined at them.

 

"Did the Osamu Dazai just say a guy is good looking or am I dreaming?" Yosano looked genuinely shocked. "You don't even call girls you date good looking?" Yosano sounded concerned.

 

"Dazai do you have something to tell us?" Ranpo chucked.

 

"Oh shut up you two, you guys know I'm not into that gay stuff, my step mom would kill me." Dazai smiled "Look if he was a girl im sure any guy including me would tap that." Yosano and Ranpo gave each other a look but decided to drop it.

 

"So where should we go for lunch?" Yosano said to change the topic.

 

"McDonalds or something?" Dazai said.

 

"Eww McDonalds?" Ranpo gagged.

 

"Look if we go I'll get you ice cream." Yosano watched as Ranpo immediately cheered up.

 

"Really?!?" Ranpo looked like a little kid.

 

"Yes really now pay attention." Yosano told both of them. After History Dazai walked next to Atsushi on there way to PE. While they’re waiting for their PE teacher Dazai decided to make small talk.

 

"Atsushi are you ready for PE?" He said mockingly knowing the boys dislike for the teacher.

 

"You know how I feel Dazai, it's been weird since we got a new teacher, he's just so robotic," Atsushi sighed.

 

"Adam? A robot? Atsushi is it because he's American? Wow I never knew you could go so low." Dazai said "shocked".


"WHAT!” “No, Dazai you know that's not what I ment!" Atsushi was blushing hard out of embarrassment.

 

"Atsushi! I can't believe you hate Americans!" Dazai said very loudly in front of Lucy who happened to be Atsushi's best friend. Lucys head almost did a 360 degree turn.

 

"ATSUSHI WHAT DID YOU JUST SAY!?!" Lucy looked like she was going to beat the shit out of Atsushi. Dazai took that as his cue to leave. Adam just made them do a few exercises in PE before the bell for lunch finally rang. Him and Atsushi left together making there way towards the group. Yosano, Ranpo, Kunikida, Dazai, and Atsushi all made their way off campus.

 

"So whose car are we taking?" Yosano asked.

 

"We can take mine its the biggest out of all of ours," Dazai piped in.

 

"You know what else is big?" Yosano whispered to Ranpo loudly but the rest of them ignored their snickering.

 

"Dazai its still not legally for you to drive with others," Kunikida said sternly.

 

"Oh come on Kunikida don't be such a downer," Ranpo said.

 

"I agree with Kunikida," Atsushi said.

 

"Come on, would you guys rather have one person in the trunk or for everyone to have their own seat," Yosano question.

 

“Fine we can take Dazai’s car.” Both Atsushi and Kunikida agreed.

 

"Atsushi you're sitting in the middle in between Kunikida and Ranpo," Yosano stated.

 

"Okay!" Atsushi is the smallest out of all of them and Yosano want music priorities not that Dazai minds. They all hoped into Dazais car and he started to take off. Yosano contacted her phone to play music.

"Yosano why is your playlist called Eat me up?" Kunikida asked, "And who is Ayesha Erotica?" Atsushi chocked on air after hearing the name. Ranpo and Dazai started laughing as Yosano had an evil smile plastered on her face. Dazai didn’t even know who the artist was but Kunikidas face was hilarious.


"Kunikida just wait, I think you'll love it!" Yosano started to play WHORE IDOL. Yosano and Ranpo started singing along. Kunikida and Atsushi looked mortified. This continued until they arrived at the drive-thru where Dazai turned down the music.

 

"Oder what ever you want, I'll pay just make sure not to spill," Dazai waved his Mori's card in front of their faces smiling.

 

"How and when did you swip his card?" Yosano asked.

 

"Oh it was easy I did it while they were fucking up in their room." Dazai smirked while Yosano whistled.

 

"There still together?" Atsushi asked surprised.

 

"Yeah she needs him for money."

 

"What is Moris job? Didn't he used to be a doctor?" Yosano asked.

 

"He was but his current job is probably like a mob boss or some shit." Dazai said, everyone chuckled like he was joking so he just played along.


"Anyways so what do you guys want?" After ordering they made their way back to campus.
