~Le time skip brought to you by angry Papyrus and pun-making Sans to befriending the skele-bros~

It's been two years since you lived in the Underground ending with a Pacifist ending. You didn't exactly break the barrier but you at least didn't kill anything/anyone. You still lived with Toriel, enjoying every moment of time you spent with her. You told her not to call you "my child" anymore so she eventually stopped. Even though you loved everyone, two people caught your eye the most. The two Skele-bros, Sans and Papyrus. The skele-bros, you loved both of them, they were like big brothers to you. Especially Papyrus. But soon you realized you were developing a crush on Sans. You would always get lost in your thoughts and stare at him from time to time for long periods of time, but he didn't mind. Toriel noticed this from you so she let you live with the bros. They excepted you in, finally having someone else than each other. You either would take Sans's bed or the couch when sleeping. Their home still felt like your own home.

~Random day~

'He's so sweet...' Yeah, yeah come on, stop making googly-eyes at him he's gonna get scared by you. 'Sorry, he's just so cute...' Omg stop with the love crap. You still were deep in thought about Sans and Zero(your second personality) had a perfect idea. Hey (Y/N). Did you ever think that Papyrus, not just Papyrus, everyone seemed a little TOO close to Sans? You noticed the emphasis on 'too'. 'Yeah and?' you spat back. They're ruining your chances in getting with him. 'True but--' No buts. Did you ever think of killing them? 'N-no! I could never kill my friends!' But you'll never get Sans to yourself~ 'F-fine. I'll think about it.' Kill your friends, you couldn't just kill them. They're your friends. You love them, in a friend way. But, they were in your way. You could never get Sans if they're in the way. Is there really any other way? 'O-okay. I-I'll kill them. For Sans.' Perfect~ Pain shot through your body, but you realized you weren't in control of your body. You can only see what's going on. 'L-let me out Zero!' Haha! Never! I'm taking advantage of your body! Soon Zero went into the kitchen and grabbed a butcher's knife. She first went for Papyrus, since he was Sans's brother and the most closest to him. Zero found him and slashed at him. "B-BUT I BELIEVED IN YOU (Y/N). T-THAT YOU W-WERE GOOD, A-AND WOULDN'T HURT A F-FLY. BUT I GUESS I WAS WRONG. WELL, I-IF THIS IS WHAT YOU W-WANT, THAN I GUESS I-IT'S FINE." Papyrus soon turned into dust. Zero just laughed maniacally. 'I am so sorry Papyrus...I wish this didn't happen...' Oh stop. Just stop. It was fun and this is how it's gonna go, k? '...' Silent treatment, eh? I'll just continue what I started. Soon enough the whole town just was filled with dust. Monsters' dust. Screams ringed in your ears and you made crying sounds in your conscience. All monsters were gone except him, Sans. Blood covered your (F/C) hoodie and black pants. "Sansy~ Come on out~" Zero cooed. Sans stayed silent in his house. Zero broke down the door to see Sans kneeling besides his dead brother's dust. "(Y-Y/N)...I've had a crush o-on you for Asgore knows how long. But seeing this monstrous side of you...I don't know what to think. Hate, anger, insanity, I don't know, heh. Just take me too, since it's just me as the last monster, there's no point in living." "Hahahahaha. I'd be glad too. One more thing though, this isn't (Y/N). She's trapped in her own mind right now while I, Zero, have control of her body. But, she did agree to killing everyone for you so it's not just might fault in this, even if I want to take full blame." Sans stares at Zero in disbelief, until he was slashed in the stomach, and turned into dust too. Ugh, there's nothing left to kill here. You can have control again (Y/N). Soon you have control of your body, down to every single toe and finger. 'Finally...' you sigh. You need a monster's soul to cross the barrier so...grab someone's and let's get going! You look around and see upside-down white hearts above every pile of dust, their souls. You obviously took Sans's soul and crossed the barrier with it. Fresh air filled your nose as you admired the sunset. 'Wow, it's been so long since I've seen humanity...' Yeah but you should find somewhere to stay since it's getting pretty dark. The woods are probably your best choice at the moment. 'Yeah...' You honestly kind of forgot what just happened in the past hour, your family getting killed and even your crush. You honestly didn't feel much pain or depression. You just shrugged it off and ran into the woods at the bottom of Mt. Ebott. You slumped down next to a tree, relaxing for a bit. You just needed some rest.

~After your wonderful dream~

You wake up on a pile of leaves and some sticks. 'Well that was uncomfortable...' No duh you slept on twigs and leaves did you think it was going to be a luxury bed?! 'Sorry...' Ugh, just, get wood or food or something...so we don't die. You search around and conveniently find a hatchet. It's bloody but you didn't really care after wiping out the whole entire race of monsters. You used it and started swinging it at the tree making dents, hoping to cut the tree down soon.

~Toby's POV~

"Did you really have to use MY hatchet as bait?!" I whisper angrily at Masky. "Shh, she found it," Masky responds. You pout like a little kid and look over at the girl. She looks like she's 15 or 16, judging by her size. Her brown, tangled hair flowed behind her as she picked up my hatchet. Masky pulled out the camera and started recording. It made a "BEEP!" when the recording started so (Y/N) had to look over at us. We ducked as quick as possible, hoping she didn't see us. After a couple of minutes, we slowly peek over the bush we were hiding beside and saw she was cutting down a tree. 'She looks so cute when she's angered and frustrated...' you think as you stare at her. Then you realize Masky is snapping his fingers in front of your face and you get out of your daze. "You okay there?" Masky worriedly asks. "Yeah just dazed out....in her wonderful eyes..." you mumble the last part. "Huh, okay." 'Wait, did he hear me?! Oh shit, shit, shit!' You and Masky keep recording (Y/N) as she does her thing.

~Your POV~

You swore someone was watching you but you ignored it. You finally got your last swing in and the tree fell down. "Phew, that was hard," you say to no one. When you go to chop the tree up more, a ghost like figure stands in front of you. "Huh?" you ask. They look just like you but different clothes...and creepy. There was horns on the girl-figurine, a devil tail, blood splattered on her clothes, an insane expression, and the same wings coming from her back except they were, bloody. Their eyes were crimson blood red, as well as blood seeping from their eyes. "H-Hello...?" you stutter.
