For once Swapfell will be in the story(just woke up and started typing)

Swapfell Sans POV

I was walking looking for humans when I heard a lot of shouting  and something what sounded like gunfire. I went to the direction of it and saw different mes fighting different mes. Then I saw what I was looking for but she wasn't an ordinary human she looked like an angel. Her dress was short kinda up to her thighs (there were shorts under it) . Her eyes looked like the night sky. Her hair went with the wind. Everything about her was perfect. 

Reader POV

I noticed another skeleton and it looked like Swapfell Sans. It seemed that he was staring at me in admiration. He then approach me and in a nice voice from his usual angered tone. He said "What is a nice looking girl doing out here fighting". I was surprised to hear that from him. I expected to hear him yell instead he was kind and showed a nice side.(If you want to have a genocide route let me know in comments cause a genocide route is epic but only effects your enemies). Nightmare came behind Swapfell Sans and hit him hard that he was close to being unconscious. I caught Swapfell Sans and carried him to Swapfell Papyrus.

Swapfell Papyrus POV

I saw a human carry Sans in her arms she was badly injured but showed strength. She handed me Sans and said that she could heal him and that he needed to rest. I let her heal him and took Sans inside and laid him on his bed. After that she went back to where she came. I ran after her and saw another me and lots of sanses. They all froze and I said thank you to the girl who brought sans home and she told me her name.

What  do you want me to name my next book since its gonna be a lemon.
