The Fallen Lovers (Underfell Sans x Female Fallen Angel Reader)

A Simple Misunderstanding

~~~~(Y/N)'s POV~~~~

You pulled the spear out of your shoulder, wincing as pain is shot through out every inch of your body. You heard a shriek, and by the sounds of it, it was Alphys who shrieked. "U-Undyne!!! Why on earth would you attack a fellow monster?!?!" Undyne stared at Alphys.

"She's human! See for yourse-" She was cut off from shock as you stood up, using the wall for support since you were shaking terribly. You had unfolded your wings, proving Alphys' point

You saw Sans staring at you with a pained look and rushed over to you, not being able to hold back the instant urge to help you. "D-don't worry S-sans, I-I'm f-f-fin-ne....." You blacked out from blood loss, falling forewards into Sans' arms. By this time Sans' right pinprick was flaring red with magic, obviously telling Undyne that if she doesn't want to die, she better leave pretty quick.

Alphys ran over to you, helping Sans lay you down on your bed until Alphys can transport you to the lab. "I suggest you leave right this fucking instant if you don't want to be sushi in the next 5 seconds." Sans growled lowly at Undyne, she got the message and even Papyrus was shocked to see the look of fear on the face of the captain of the royal guard.

When you woke up there was a metallic taste in your mouth, the taste you knew of your own blood. As you sat up you hissed in pain as your shoulder was throbbing. You saw Sans walk in through your bedroom door, holding a glass of water, and glass shattered on the ground when he saw you were awake. He ran over to you and hugged you so tightly that it was as if you would fade away if he let go. You hugged him back, laughing softly.

"You act like you haven't seen me in years, how long was I out?" You ask, but your lazy smile was darkened into a disbelieving frown. "You were in a coma,       (Y/N), for 7 weeks...." Sans whispered, as if it hurt to say those words. He hugged you tightly again, crying softly into your shoulder.

"You flatlined 11 times in the first week, I was worried you weren't going to make it. I was scared at the fact that I might have had to live without you. Don't ever do that again, you scared me so bad that I wasn't able to sleep at all at night until I passed out I-I....I...M-missed you, s-so much...." You pulled back from the hug, and almost instantly Sans' teeth crashed into your lips, pulling you into a desperate kiss that you returned, knowing the mixed feelings of fear, sadness, anger, and worry that clouded his thinking. The kiss soon turned into a series short, soft kisses. By now you knew no one else was home because they would have ran upstairs then cup had shattered on the ground.

"I love you (Y/N)..." Sans said in a hushed tones. You placed you forehead on his, whispering back,"I love you too, Sans.." The skeleton pulled you back into another hug, but not as tightly, and he soon fell asleep like that, so you pulled him onto the bed, laying him down and pulling the covers over him. You wiped away the last of his remaining tears off his cheekbones.

You got up off of the bed, walking out into the hallway, and going to a side closet with the broom and dustpan in it. Bringing the broom and dustpan back into the room, you swept up the glass shards so no one would step on them.

After recreating the cup using your magic, you go lay back down next to Sans, whom immediately grabbed ahold of you when you laid down. You snuggled your way next to Sans, and you rested your head on his chest, which was surprisingly comfortable since he was a skeleton.

You jolted awake when you heard the front door slam, which also woke Sans up. "Paps is home, come on, he'll be happy to see that you're awake." Sans gently pulled you up off the bed like you were a fragile China doll, and opened the bedroom door for you to walk out into the hallway.

~~~~(Sans' POV)~~~~

"Hey! Papyrus! (Y/N) finally wo-" My words just stopped then and there, seeing whom I though was Papyrus, but he, no it was there instead, the last person in the underground I would want to see, there, at the bottom of the staircase, he stood, with his grin growing wider when he catches sight of (Y/N).

"Sans, what's wro-" (Y/N) saw him, and she knew his aura was powerful and dark.

"So this is the monster with the soul more powerful than any other soul I've ever seen, I've been looking for you, you know, you shouldn't keep secrets, especially if it could decide the fate of an entire race."

(A/N Cliffhanger!!!! My specialty, just by the way. So what do you think so far? I currently have the next 10 chapters roughly drafted in my head right now, and trust me, this story is only going to get better. See you next chapter, Author~chan out!)
