Yandere Nightmare sans x Male reader

Who was that?

Y/N's pov
Huh who is that guy you asked yourself.They just keep appearing at the end of every nightmare.(A little fun fact you know about the AUs and nightmare is going to use that to his advantage)I should probably get something to eat then head back to bed you said to yourself while getting up from you bed and went downstairs.Ok let's just get some milk-.you couldn't finish your thought as you heard a crash behind you making you turn around so fast you would have sworn that you had did a spin you then saw a injured goopy skeleton that made you finally remember what that guy in your nightmare's had looked like.You ran over to the skeleton picking up his unconscious body carefully not to hurt him and brought him up to your room and onto your bed and left to get to go get bandages and gaze.when you came back he was still unconscious so you were able to slowly take off his jacket and shirt and started to warp bandages and gaze around the areas of injuries and when done you went back downstairs to get a drink for him when he wakes up.once you were done with that you went back downstairs again to sleep on the couch.

Did it work? I asked myself.I tried to get up out of a bed but was stopped halfway due to pain making look down at my chest to see bandages and gaze over some of my bones.So I used my magic and tendrils to get on my feet and left the room to go downstairs to see who helped me.When I got downstairs I couldn't find anyone but when I got to the couch I saw a male but it was the male that I was obsessed with making me blush at the thought of him taking off my jacket.With a little bit pain I went back upstairs to Y/N's room to his bed and fell back asleep ready to take what's mine in the morning.
