Sans P.O.V.
It had been a few days since we discovered that Undyne was killed. (Y/n) wasn't at all herself. She was avoiding me, as much as possible. It was like she was hiding something from me.
I wasn't sure what to do when I tried to kiss her again that morning and she rejected me.
Maybe the fact that her sister had killed so many people, including Papyrus.
Maybe I shouldn't have kissed her. Maybe it changed things between us. Maybe it ruined the relationship. Shit...
I watched as (y/n) walked past me, avoiding eye contact. I gritted my teeth and I shot up, following her into the kitchen.
"Hey? Kiddo?"
"Please.. don't call me kiddo."
"Okay, (y/n). Mind telling me why you are ignoring me? Why you're being defensive?"
She sighed, "I'm not being defensive, Sans. Nor am I ignoring you."
"Like hell you aren't! You have hardly said two words to me since we found Undyne. You won't even make eye contact with me!"
"I'm sorry. I'm just.. depressed okay. My sister is.. ya know," She grabbed a cup out of the cupboard, making he way to the sink.
I tightened my fist, getting slightly irritated, "(Y/n). I know your sister is doing horrible things, but I can at least help you deal with it."
"Sans. You can't help me right now."
I snapped. I grabbed her wrist, actually causing her to wince and drop the cup of water. Water splashed all over to floor. I could see fear in her eyes.
I tried to calm down, but I wasn't happy with the situation, "Look. Do you think this is easy for me? It's not. I lost my brother and the only person I have left is trying to ignore me for reasons I don't get! Why can't you just let me be here for you?!"
Her arm shook in fright beneath my grip. I let go, walking to the other side of the room, putting my hand over my forehead.
I looked at my hand, and that's when I noticed something.
I had blood on my hand. I looked over to (y/n) who was quickly trying to adjust her sleeve.
She had been wearing that same long sleeved shirt since we found Undyne. Why?
I sighed as I turned away from her, "If you want to deal with this by yourself, go right ahead. I'll be in my room if you need me."
And with that, I walked out of the kitchen and up the stairs.

Your P.O.V. (First Person)
I watched as Sans walked up the stairs, leaving me with a large puddle before me and a hole in my heart.
What was I doing? He was right. I was ignoring him. I was avoiding him. Not because I wanted to, but because I didn't want him to have to feel the horrible feelings I had inside me.
I walked over to the couch and I sat down, my thoughts screaming at me.
Maybe, I'll take a nap..
I laid down on my pillow, hugging myself in agony. I let my thoughts drift away, allowing me to fall asleep.

I stood in a hallway. It had a checkered tile and there were pillars running down the long hall.
I could see Chara.
She stood there, a knife in her hand.. blood dripping off of jt. I approahed her, my legs suddenly feeling heavy, not wanting to move.
Sans came into view, but.. he was on his knees.
As I got closer, I could see blood dripping from his chest. I ran quickly over to him, "Sans!!"
But.. he couldn't hear me. I-I was too late.
He slowly looked up, as a tear fell from his eyes, "P-Papyrus? Do you want anything?"
I watched in terror as he turns to dust, a pool of blood surrounding where he had been. No.. no..
I heard the sound of hysterical laughter. I turned to see Chara giving one last laugh before saying, "He did it for you ya know. He thought he was saving you, the fool. But he should have known... that you will never be safe."
She laughed again, her red eyes piercing through me.
"See you in hell, (y/n)."

I woke up, a cold sweat all over me. Luckily, this time, I didn't scream. What time was it?
I looked around to the clock hanging behind me, above the couch.
6:49 p.m.
Has Sans come down stairs?
I stood up, heading to the kitchen. To my luck, he stood by the sink, his back to me.
He obviously didn't want to talk to me. I turned to go back in the living room, but his deep voice stopped me in my tracks, "Where do you think you are going?"
I turned to see he still hadn't turned to face me. I sighed, "What do you mean?"
"You didn't come in here just to see if I was downstairs and then leave, did you?"
I gulped slightly, looking back towards the living room.
"Well.." I began but stopped myself. I wasn't sure what to say. I felt bad for ignoring him for my own selfish reasons.
He finally turned to me, weary eyes staring into mine, "Nothing to say, huh?"
I bit my lip as I said, "Well.. I um... I just.."
He sighed as he walked up to me, suddenly only a foot away. I couldn't help but want to kiss him. The urge spurred through my head over and over.
"(Y/n)?"
I starred into his eyes. His beautiful blue eyes..
"Yes?"
He was quiet for a second, before he came close enough to whisper, "I love you."
