Flash back to a previous time

In the au known as Underplayer everything seemed fine, but there was a something terribly wrong with it. It had many problems, bugs, cracked code and unrefined character placements. It was due to the results of Player attempting to access a thing beyond the ending of the game. Player restarted the world once again as they attempted to do it once again.

"Come on! C-C-C-C-C-C-C-C-C-Come on-on-on-on-on!" Player said as the entire universe began to glitch and fracture into pieces until they stomped, exhausted from the effort.  Player floated disappointed in their efforts. 

"Wow, you did pretty good. Maybe when your done you might delete yourself" 404 said as he was floating behind her steaming sarcasm. Player turned around unamused.

"Your supposed to be helping me! Core said-"

"Core is a child and a optimist. They has no idea what the real world is like. Look its clear that this Au had a endpoint. Why in the hell are you trying to extend past it?" 404 asked annoyed

"I want to give everyone a happy ending, ever since I played undertale for the first time I've dreamed of what lies beyond the credits and what life for everyone is like after." Player said looking at the barrier. 404 stared at it too.

" Not all stories need more to be a story. The best part of every story is the ending." 404 said as he crossed his arms.

"Heh wow, that was almost poetic, maybe in another week you'll sing me a song." Player giggled, for a short moment 404 was reminded of Chara, his adorable smile and sweet laughter. 404 then groaned as he destroyed the barrier.

"What are you doing?" Player asked

" Testing something. Close your eyes." 404 said, Player closed his eyes and began to hear the sound of code being shifted and moved around, data being used and deleted until...

"Ok, open them." 404 said, when Player did they saw a whole wide world beyond the barrier and beyond the credits of the world had been created.

"Woah! But, my friends. Will they be able to-"

"Don't worry, All I really did was make your universe bigger. It's a simple process really...I could teach you...if you want." 404 said stuttering a bit while still trying to sound like himself. Player than ran to him and hugged 404. 404 didn't know how to react and just stood there.

"Thank you, William." Player smiled his rosy lips and cheeks full of color and life , 404's face turned a bright red as he looked away and then removed himself from the hug.

"Ooook, thats enough physical contact." 404 said

"Oh sorry, I guess you are a error. I know you guys don't like being touched." Player said

"No its not that." 404 said

"Then what is it?" Player said tilting his head.

"Its uhh...its uhhh.." 404 looked down to Player whoes hair was shinning in the light of the surface. Another reminder of Chara

"I.....I'm betraying myself." 404 said as he sat on the ground, Player back up as he looked at 404 put his head in hands.

"Uhhh are you ok?" Player said, 404's eyes opened wide ad remembered where he was, He then stood up straight and walked away. Player watched curious before then leaving to explore the new world 404 had made. 404 walked past hundreds of faces he knew, mettaton, muffet, undyne and many others. He walked all the way to hotland. He then looked over and saw the laboratory. He could feel his memories flooding in around him, hallucinations of his child self running around hotland with Adam, Ares and Jacob clouded his mind. He could see them and yet he couldn't interact with the past. 

"Hey pal. Don't you wanna turn around and shake my hand?" said a voice

"No thanks." 404 said as his face fell to a stern and frustrated look as he waved his hallucinations away. He looked back to see Sans or better known as Player!Sans since he was in Underplayer. 404 looked at his hand to see there wasn't a woopie cushion in it.

"What? were you expecting something?" Player!Sans asked

"...No." 404 said

"Heh, alright then. So what brings you to hotland...taller me?" Player!Sans asked as he then got a comb and began to comb his skull. 404 looked at him oddly before looking down at the lava below.

"I don't know, old memories just came back to me and I...Decided to come here I guess." 404 said as he put his hands in his jacket, something he doesn't normally do.

"Sounds like your running from something or maybe someone? I don't know, who am I to judge." Player!Sans said as he then began to eat a catdog. 404 looked down at the lava with a melancholy like look. Sans looked at him and then sighed. 

"You know, I know a killer spot. Has some of the best burgers in all the underground." Player!Sans said as he walked next to 404 and patted him on the back.

"Don't touch me." 404 said

"Ok ok. Say no more. So what do you say? fancy a burger?" Player!Sans asked, 404 looked at him completely indifferent to his request. This simple bundle of code, he didn't think anything of it. This Sans was simply just following a set of As and Bs, answering what he could without breaking character. 404 felt himself different as he wasn't restricted to no script or grand plan. He was free from whatever hold these universes had on its inhabitants. 404 simply pushed past him and walked away. He didn't know where he was going, but it was somewhere. 404 walked so far away until he eventually ended up in waterfall where he could see a lonely statue. 404's eyes then began to see memories of him, Adam and Frisk messing with it. 404 then shrugged as he kept walking. He walked until he found a lonely bench in waterfall where he would begin to think about his previous interaction with Player. 

He felt like he shouldn't have been feeling the way he did, he loved Chara, every inch and aspect of him...however he also felt like he was restricting his own happiness by not allowing himself to move on and be happy with another person again. He felt a undying dedication to Chara and his image and yet also that he shouldn't feel that. Maybe he wasn't in love with Chara anymore, just his thoughts and ideas on what Chara was and who he hoped and wanted him to be in the past. Less controlling and more free, less showy and more reserved. Everything he was. Maybe he desired someone like himself.

"Love is a unpredictable algorithm, I hate that I can't understand it, I hate that I can't control it, I hate that I can't be free of it....I hate myself for feeling it. Why in the fuck did I blush to that stupid jumble of code.

Maybe one night wouldn't be so bad...no, Chara is my one and only, I shouldn't even be thinking about anyone else." 404 said to himself. 404 then thought about his goal, Alphatale...Chara, Adam and everyone were so far out of reach. He had spent so long in this multiverse and had gotten nowhere, the alphatale code was nowhere to be found. Those unique sets that made everyone who they were, made him who he was. There was no way to recover them, no way to bring them back. 404 didn't even realize it yet, but he started crying with a straight face his eyes not even twitching from the tears.

"Sometimes, I wish I could have just died along with the rest of them...What am I doing still alive? Why do I fight for my life so much if I always end up feeling this way? Why do I do anything." 404 said to himself as he leaned back. He then looked at his hand and then to his finger. He then began to start up his god ray, 404 closed his eyes as he then aimed it right at his head.

"I'm so tired" 404 said, that's when he suddenly heard shuffling and then jolted up, he looked over towards the bridge that led to the lonely bench. 

"Hello? 404? You around here?" shouted the voice of Player, 404 looked over and then to his finger which still was ready to fire the god ray, 404 put it to his head and closed his eyes as tears rushed down his face.

"COME ON! DO IT! DOOO ITTT!!" 404 shouted to himself in his head, he then heard the footsteps of Player getting closer and closer. 404's eyes then opened slowly. He gave a deep sigh. Player then rounded the corner and saw 404 calmly sitting on the bench by himself looking forward.

"There you are, I was looking all over for you." Player said as they stood near the bench.

"Hey, Enjoy the world? Took me hardly any effort." 404 said as he then picked up a echo flower.

"COM-" 404 then crushed it before it could repeat what it last heard.

"Aren't they beautiful?" Player said

"Hm? what these flowers? They're annoying." 404 said as he tossed the crushed one into the near river. 404 then leaned back as Player then sat on the bench. 404 and Player just watched the waterfalls and rivers churn. Life was blooming everywhere here, even though it was all underground it didn't matter. Life was still blooming. 404 looked to Player whoes hair was flowing in the wind of waterfall, He looked to him and thought of Chara once again. He then shook his head as he looked forward again. 404 looked out to the many monsters lingering around staring at the beautiful waters too. 

"Hey, I was thinking maybe you and me could watch a movie later today, to celebrate the creation of the true happy ending of this world! The lives of these monsters are gonna change for the better here and its all thanks to you." Player smiled as 404 looked at them indifferent.

"I'm no hero." 404 said

"Nonsense, Look at all the good you just did and you did it in a few easy moments. You could help make the entire multiverse a better place for everyone. Maybe even give those lost Aus in the omega-timeline a home." Player said

"...No thanks. Being a goody two shoes isn't my thing you can ask my brother that." 404 said, His eyes then jolted open when he mentioned Adam and he then covered his mouth instantly however it was too late.

"YOU HAVE A BROTHER!? What are they like? Does he look like you? Are you both the same age?" Player then began to blurt out questions, but 404 wasn't having any of it as he then got up and walked away. Player noticed and followed him.

"Wait where are you going?" Player asked

"Away." 404 answered

"What why? We just got started, there are still bugs and stuff that needs fixing."Player said, 404 scoffed as he stopped and then got up his digital screen and began to work on Underplayer's code, but his frustration and irrational behavior was causing him to do sloppy work.

"404 stop." Player said

"I got it." 404 said as he kept working

"No you don't." Player said

"Yes I DO." 404 argued

"Your messing up the code." Player said as he then grabbed at 404's arm, but he wouldn't budge a inch.

"Just let me fix this." 404 said as his eyes began to get watery, he then began to rub at them. He shouldn't be crying, why was he crying. He wasn't sad, theres nothing wrong with him. He didn't need fixing. His hands began to shake uncontrollably.

"Are you ok?" Player said extremely concerned 

"I'M FINE!" 404 said in a sorrowful voice, Player then finally jerked his hands away from the screen.

"WILLIAM STOP!" Player shouted, it was over. 404 couldn't hold anything in anymore. He fell to his knees. Player still holding his hands as they looked at 404's empty watery sockets as tears fell down his face faster than the waterfalls around him. 

"...I really tried...I always knew it was hopeless. I just didn't want to believe they were gone. Not because of me. I don't want to live in a world where I'm the only one who knows the truth." 404 cried, Player looked at 404 crying. it was weird seeing someone who looked to be so powerful, someone who looked to have it all together crying. Player shook those thoughts away as he then embraced 404. He the hugged Player grabbing onto him tightly. 404 then began to mumble as his face was planted in Player's coat.

"What?" Player asked, 404 then removed his head from Player's coat still crying.

"Did you know that, a shrimp's heart is in its head? and that a crocodile can't stick it's tongue out?" 404 said, Player giggled and then laughed. 404 looked at him.

"Your such a cute dork." Player chuckled, 404's face lingered on Player's as he could feel all his frustrations, sexual frustrations, urges and raw emotions melt onto his very person.

"I knew everything about Chara, I knew his favorite color, I knew his favorite food." 404 thought to himself. He then grabbed Player's face, Player stopped laughing and then looked at 404 who was staring at him too. the two looked at each other and didn't hold anything back, no regrets to linger or weigh on them, no past relationships to have them thinking twice. It was just this moment, this raw moment. 404 and Player passionately kissed one another.

"I fall in love too quickly." that was the last thought to go through 404's mind that day.
