-----*^*-----

Apparently, you had fallen asleep on the couch. But when you woke up, you had no clue where you were. Your muscles ached, and you felt like at least one of your ribs were broken. You mentally groaned as a thought came into your head. Were you at your father's house again? Had you never ran away?

You squinted, trying to see anything around you in the pitch darkness surrounding you. But as soon as you moved, a sound came from behind the door and it opened. A silhouette of some tall figure appeared and your heart started thumping harder.

"Don't move a bit, you little SHIT!" The figure yelled, and you winced. It seemed to be stomping towards you, and before you knew it, it grabbed your shirt's collar and lifted you up from the ground.

"Look, I feel.. Sort of bad about taking you from Papyrus, but he doesn't matter much to me. You on the other hand..." It hissed, and the voice seemed deep, yet feminine. "Your soul will be MINE!" She yelled, and the room lit up with hundreds of floating red spears. You squealed loudly, making the figure flinch.

You examined your capturer. She had blue skin and gills, appeared to be a fish, and had red hair. She was wearing uncomfortable looking armor with a broken heart at the center of it. You swallowed hard, for she looked like she would kill you in a heartbeat. And the eyepatch made it all scarier.

You screamed as one of the spears poked your spine, followed by about five others. You screamed again louder this time, struggling as they kept coming. You tried kicking the fish lady, but she avoided it easily, laughing at each attempt.

"Don't even try, you little shit," she growled, showing off her sharp golden teeth. You tried kicking again, this time landing your foot on her shin, making her drop you in shock. "I SAID DON'T EVEN TRY!" She growled again, making you wince in fear.

"H-help!" You yelled, but you knew that no one would hear you. You held your left rib cage, which was bleeding because of a spear. "P-please.. Someone.." You tried again, running out of breath quickly. You were tired of being thrown around like a piece of garbage.

She threw yet another spear at you, this time hitting your side, and she grinned, hearing your yelp of pain. "No ones going to hear you, you little brat-" she said, but she got knocked into the wall as a red aura surrounded her. She growled in frustration, looking for whoever attacked her.

You looked too. Whoever saved you, at least you thought saved you, was a true hero.

Black jacket. Red sweater. It was Sans. He was growling and had one arm thrown out besides him. "Look, Undyne," He spat out her name like she was a nasty taste in his mouth, "We had her first, so fuck off!" He yelled, sending her crashing into the opposite wall.

"SANS! You idiot!" Undyne spat, holding her side, which had been rammed into a table in the corner of the room. "When Asgore finds out, he will KILL you!"

"Oh, he won't find out. Because you're not going to tell anyone," Sans replied casually, yet he was gritting his teeth fiercely.

"I will! And Asgore will-"

Sans laughed, interrupting her. "No no, fish lady. I'm going to kill you if you even think about telling someone." Sans said, making Undyne silent. "Now, give me the kid, or else." He said, his hand still out, ready to slam her against something again if he needed to.

Undyne nodded, gritting her teeth angrily. Sans slowly started towards you, keeping his hand out to attack if she tried anything funny. He took a look at you, showing no emotions except for anger. You were bleeding. A lot.

He let go of Undyne and offered you a hand, but didn't actually offer it to you. He just pulled you up harshly, making you yell out in pain. The spear that had hit you in the side was aching more than ever, and a large gush of blood was pouring out of it. You held your wound, wincing.

"Come on." Sans demanded, glaring at Undyne. You wondered why he was actually concerned about you, or why he had come to rescue you. You nervously, and painfully, made your way across the room, and Sans guided you out of the building.

"Let's just hope nobody sees you..." Sans said, looking around before he took your hand and pulled you across the road, since you were limping. His touch made you feel weird and uneasy, but you didn't pull away for some reason.

He was forcefully tugging you across he street, and once you got across, you were already at his house. You groaned out of pain, and slowly entered Sans's house. "Just sit down. I'll get something to help you," Sans said, and you agreed, sitting down on his comfortable couch. You held your wound tighter, ignoring the smaller one that was on your left rib cage. You sighed, squeezing your eyes shut.

A couple minutes later, Sans came back with gauze for your wounds. You wondered why he was carrying gauze around, since he had no blood, but you shrugged it off mentally. At least he had something for you.

"Sit up.." He said softly, and you did, uncovering your nasty wound. "Ugh, I'm glad I can't bleed," He said as he handed you some gauze for you to wrap around your wound. You weakly took it and began to slowly wrap it around your waist area. Sans sat down on the couch next to you, crossing his arms. He didn't say anything.

You slowly sat back, feeling a bit uncomfortable. Although, you were grateful for Sans's help. You didn't know what to say, but you were extremely happy that you didn't dream of the escape, and you were actually back at your fathers house. You sighed as the memories flooded back into your vision.

"Hey, (Y/N). Sorry for being so rough with you earlier. I know it must be tough for you..." He said, but he avoided eye contact with you.  You felt a smile creeping onto your lips.

"It's okay..." You replied, and Sans looked over at you for once. You weakly smiled as Millie leapt up on the couch, noticing you were hurt. She meowed, concerned, and settled down on your lap.

"Yeah." He answered with a small grin.
