Undertale Scenarios

Prompt #1 - Heartbreak Scenario

Warning: contains swearing, vulgar language and may cause extreme cases of crying, wailing, wanting to kill yourself because of the cringe and disappointment in the author. Proceed with caution. You have been warned.

The rain pitter-pattered dismally against the window as you strode lazily in your PJ's. Definitely no going out today, what with what looks like rain for a whole day.

Your hand ghosted over the remote control. You hesitated. You weren't sure you wanted to see Mettaton's face - the face of a friend of someone you wanted to forget.

Don't think about him. He doesn't deserve to be loved by scum like you.

You inhaled sharply. A quick, short feeling of self-loathing washed over you, almost possessing you.

Your hand closed around your neck and massaged your throat idly. How wonderful it would be, how convenient, if you could just squeeze your hand and slowly painfully drain you of your life-

. You crumpled into the sofa, pushing your knees to your chest as the tears began to flow. Ugly sounds came from your mouth, chokes and gasps because God you missed him so much, so much it hurts. You couldn't bear to be where he wasn't, but you had to because you hurt him, you broke his heart and he found someone else and-

Knock knock.

You gasped, throwing your head up from the crook in between your legs. You could remember the way he knocked. Solid-sounding from his firm bones, yet gentle so as to not aggravate the delicate things that were his hands. It was a careful balance that embedded itself into your mind. Like the way his mouth twitched when you managed to crack a wonderful pun, or the way he walked carefully in slow, measured steps when he was tired. Like how he writhed and squirmed under your touch in your most intimate moments together, or how he pushed himself to run with you every morning because he loved you, he cared about you and you broke his heart-

Knock knock. Knock. . . Knock.

You breathed slowly. You weren't sure you wanted company in your miserable apartment.

"Go away," you whispered, though you doubted they heard you.

"(y/n)? you in here?"

Your voice caught in your throat. A vague feeling of relief, mixed with fear and self-hate, seemed to dictate your movements.

And it said to run to the door.

You were able to restrain yourself enough to not open the door, though your hand hurt when it slammed against the cold doorknob, forcing a hiss out of your throat.

"(y/n)? is that you? are you okay?"

"Sans, please!" you cried."Don't. . . Talk to me. I don't want to hurt you like before."

"you never did. just come back home, babe. every time i sleep with the spot next to me empty i die a little more inside. it hurts when i wake up to make breakfast for one person, when i have nobody sitting across me late in the evening, when you're not there. (y/n). . . i miss you."

Something stirred in your heart, but you held yourself back. You weren't going to give in and make everything, the hurt and the heartbreak, happen all over again.

"You're lying, Sans. I know you found someone else to love, so please don't bother the one who broke your heart to break someone else's. Toriel doesn't deserve to be hurt like that. You love her, don't you?"

"of course, but. . . i've never found someone to replace you because there's that part in me that won't stop caring about you. tori is a wonderful woman, but i can't abandon you for someone who is like a mother to me."

"You deserve better!' you finally blurted out. "I left because I'm a piece of trash, that's all I ever fucking was to you and I was just some useless burden for you to carry! I wasn't committed and all those people I ever cheated on you with is enough proof of that! I left so that-so that-" the tears flowed freely now. "-I could be as much of a fucking slut as I was when we were together without hurting you."

Silence. Bless that soul, maybe he finally understood. Maybe he could finally be happy now, and leave you. . .

"so tell me, (y/n), how many people have you hooked up with in the three months you were away?"

You choked on what seemed like air.

"N. . . None," you admitted quietly. "I missed you too much to. . . God. . . ." you buried your face in your hands.

"(y/n). . . come back to me. open the door."

Your hands were shaking as he entered.

"Sans. . . I'm so sorry! I'm so-so fucking stupid! I don't know why-" your words were cut off as a pair of loving arms captured you.

"it doesn't matter what you've done. you've never hurt me. . . not once. you're beautiful in my eyes, you're worth something even with all the people you've been with that make you supposedly 'disloyal'."

Ahh, the temptation to make this turn out sad was overwhelming! But I overcame it. . .

This string of one(most likely one to four)-shots features Reader experiencing great heartbreak (or the aftermath of it) with varying cases and endings and reactions. They will be paired with an Undertale character and I will slowly work my way through the main characters to the side ones.

One thing to note is that I'm only doing this cause I got no requests lmao

Edit: fuck it I'll just make this a prompt because you can only have so much drama to write amirite up top 🖐
