A/N: Requested by MettatonThePinkRobot
Falling, doing several runs, you know what you did. But still, you continued as though there were no consequences. As if you were the one in control. Still, you couldn't shake the feeling of being watched by someone who wasn't really there. At least, not yet.
After killing Asgore and making it to the 'end', you were met with an endless darkness. Was there someone here? No-one was here...but there was. You turned around, and were met with a teen boy (yes, i'm making this chara a boy).
"Greetings, I am Chara," they state. You meet their eyes, and blush lightly. Something seemed...different about Chara. Sure, all the monsters were...yeah. But something was different about them. You just couldn't tell. As you tried to figure out what was going on, Chara finished his speech. You were given the options, ERASE and DO NOT.
You faltered. If you erased the world, would it reset? Would you be able to restart? You selected DO NOT. Chara gave you a puzzled expression, while yours stayed emotionless.
"...No? hehehe~ S I N C E W H E N W E R E Y O U T H E O N E I N C O N T R O L ?" they swung their knife and you dodged in a nick of time. You had little time to fight back, only dodging. You were determined to go back. As you continued to 'run', you pulled up the reset button, re-appearing on the bed of golden flowers.
You made it through the underground without incident. But as you approached the 'Undyne Area', the watching feeling came back. Looking around, you saw Chara. You wanted to run, but you stayed frozen.
"Oh, so now you see me? little Y/N, you wont make it to the surface and stay there in peace," he says. You shake your head, blushing lightly. You turned away and continued. You made it to Asgore, sparing him and breaking the barrier without having to die.
~time skip~
Its been a year since monsters were set free, and you felt...ok. Chara, being a ghost, wasn't able to be seen by anyone accept you. Eventually, you decided to go back to the underground. You made it to the true lab, and began looking for something. A certain entry...and you could set Chara free.
Entry Number 22
I came back, only to see the monsters that had 'fallen down'. The amalgamates are acting different. They say they saw someone come into the lab and tell them that they could live with half a human soul, and the human could still live on.
Entry Number 23
its true.
After you found the entries, you walked to the DT Extraction Machine. You flipped several switches, and (eventually) split your soul in half. And lived. Chara had been watching, but was surprised when you came out alive.
"Now what?" he asks. You hold out half of your soul.
"I wanna see if this works," you whisper. "now take it,"
"But..." Chara sighed, then mumbled something you couldn't hear before absorbing half of your soul. You turned away at the bright flash of light, turning back as the light died down. Chara was alive. You immediately hugged him, but let go soon after.
"It worked!" you whispered.
"I guess it did..."
"Should...we go back?" you ask. "To the surface,"
"Yeah I guess. Mum and Dad would like to see me again,"
~on the surface, several months later~
Chara often stayed at your place, but he didn't mind. However, you were having a hard time on confessing. You didn't want to ask anyone, and stayed in your room, thinking. A lot of the time you would think to just tell him, but your shyness backfired every plan.
You decided to go for a jog. You changed into workout clothes and left. It was quiet for a weekend. You stopped after a while to check the time; it was getting late. as you were walking home, you were grabbed from behind and met the eyes of your ex, (ex name).
"The heck do you want?!" you said, struggling.
"Something I didn't get when we were together," he said.
"Get off!" you screamed. "Siri, dial Chara!"
"Your not getting out of this that easily," (ex name) said, slapping you.
"Chara, if you hear me, head to (fave shop), i'm trapped in the alleyway!" as you finished your panicked call, (ex name) smashed your phone. You tried to move, but your ex had you cornered. as you were closing your eyes, you saw a shadow move, and your ex fall to the ground.
"You ok?" it was Chara. You nodded, ignoring the bruises on your shoulders. "No you're not. Lets get you home,"
~time skip~
You were on the couch, wrapped in a blanket and watching (fave anime). You were also sitting in Chara's lap, blushing like a tomato. You didn't want to move, so you leaned back and closed your eyes.
"Sleepy, huh Y/N?" he asked. You nodded. Chara turned off the TV and picked you up, carrying you to your room.
"Chara? wha...?" you went to object, but felt a pair of lips meet yours. You realise it was Chara, making you blush harder if possible. As he pulled away, he crawled into bed with you as you fell asleep.
"Goodnight Y/N," he whispered before falling asleep.
