▪Never Forget▪

The words melted my heart down until there was nothing left. It was official. I had fallen for a pun-making skeleton. Who knew right?
"S-San-"
I was cut off by Sans leaning and kissing me so quickly that I stumbled back. He caught me, bending me down and lifting my legs into the air.
I did the only thing I felt I wanted to do. I wrapped my arms around his neck and kissed him back.
My mind was a circus. Too many thoughts were going on in my head, but the main attraction stuck out more than the rest.
He set me back up straight, breaking away with a needy inhale.
He stared into my wandering eyes, as the words finally left my mouth, "I.. love you.."
The words seemed so foreign, yet right. He gave me a smile and then pushed me up against the wall, grabbing my hands and putting them over my head.
"(Y/n)...."
Oh god...
I tried to hold in my slight pain because of the grip on my cut wrist, but I was more worried about him seeing it. I hoped the sleeve would stay up.
He gave me another kiss, this time his tongue made its way into my mouth.
Shiit... What do I do?!
I had begun to quiver beneath him and my mind became foggy.
When he pulled away, I expected him to do something, but he didn't. When I opened my eyes, he staring up at my wrist.
No! Shit!
He backed away from me, his grip still on my hand as he pulled it towards him and studied it. I could feel him trembling as he said, "Did you do this?"
His tone was dead serious and that's when I knew I wouldn't be able to hide it.
"N-No.."
He growled, "Who then?"
I bit my lip, for some reason not wanting to tell him, but he knew anyway. He dropped my hand and gritted his teeth, "That little brat cut you and you didn't tell me?"
His voice was no where near calm, but hadn't quite reached yelling.
"Sans.. I can explain-"
"No! Your own sister cut you and you think I shouldn't know about that?!" He finally looked back up at me, his eyes full of anger and hatred.
"Sans..."
"This has gone on long enough. I am not going to let her hurt you or anyone any longer!"
He walked out into the living room, but before I could follow him, a set of bones shoot up out of the ground, blocking the kitchen.
"You are staying here. I can't risk you get hurt anymore."
"No! Sans! Please! Don't do this!" I begged, grabbing onto the bone bars and shaking them as if I could get them undone.
"I'm sorry. But she can't keep doing this. She obviously isn't going to stop."
Before I could protest, he teleports, leaving me alone in his kitchen.
I was worried. I didn't want my sister or Sans to get hurt.. Maybe I could stop them before they hurt each other...
I began to pound at the bars, failing immediatly. I growled as I turned and grabbed a chair off the ground and threw it at the bones.
At this point, I didn't care if stuff was broke.
Two of my favorite people would be broken soon if I didn't do something.
I ran over to the knives and grabbed the largest, sharpest one and I ran over to the bones.
I saw at the bone, dust slowly flying into my eyes.
"Come on," I mumbled angrily, sawing even faster.
"Come on.."
I couldn't lose them. Not now. Not after all that's happened.
The thought of losing them was overwhelming and the momentum cause me to saw even quicker.
The bone was halfway done, when the knife began to become dull. The instant I pull it from the bone, all the bone I had sawed away reappeared.
I threw the knife across the room, "Dammit!"
I looked around and then I spotted it. The small window above the kitchen sink. I gritted my teeth as I said, "Let's do this."

Sans P.O.V.
I stood in the hallway that led to Asgore's throne room.
I could see Chara at the end of the hallway. Her smile was disturbingly wicked.
"Hello comedian," She said, her voice surprisingly much more monotonous.
I gritted my teeth, not saying a single word. My blood was already boiling and listening to her speak was enough to make me erupt with anger.
She snickered walking towards me. She eventually got about two yards away from me and gave me a smirk, "Don't feel like talkin', huh?"
I growled, "Take one more step and I will make you regret it greatly."
She smirked and took a step towards me, tempting me even more just to strangle her stupid neck.
"Fine. I didn't want to have to do this," Ha, Of course I wanted to, "But... I'm afraid I have to."
Chara took out her knife from behind her and gave me a petty smirk.
"It's a beautiful day outside. Birds are singing, Flowers are blooming. On days like this kids like you..
