Sorry it took a little bit
--------------------------------------------
(G-Sans POV)

I was watching (Y/N) play with a few toys I got her it had been a few months since I found her so she was able to sit up on her own. I saw Papyrus walk through the door and he looked mad "rough day" I asked "when is it not a rough day" he sounded annoyed. (Y/N) looked at him and held her hands up like she was saying 'up,up' and Papyrus was happy to pick her up. He loves (Y/N) about as much as I do, "so what do you want to do today (Y/N)" Papyrus asked her. "How about we take her to Waterfall I think she would like the echo flowers" I suggested, "ok" Papyrus replied and started getting (Y/N)'s stuff.

(Time skip)

We were in Snowedin, I put a jacket on (Y/N) so she wouldn't freeze, Papyrus and I took turns carrying her. I was carrying her and she was hugging a stuffed animal I had gotten for her she looked like she was falling asleep so I let her rest until we got to Waterfall. When we finally got there I put (Y/N) down and sat by her, she started crawling over to an Echo flower and reached up for it and when she touched it she giggled 'I guess she is going to be one of those people who see good in everything' I thought as I watched her. Papyrus looked at her and walked over and picked her up so she could see the flower better. She grabbed it gently and Papyrus said something and when the flower Echoed (Y/N) giggled even more. After a few hours of playing around we left and went back home, when we got home (Y/N) started to cry a little "are you hungry sweetie" as soon as those words left my mouth (Y/N) was quite, I laughed to myself and walked into the kitchen. I grabbed one of the bottles and warmed up some milk, I fed (Y/N) and then she fell asleep in my arms. I put her in her home made crib, then went to bed.

"Sans......someone is at the door and it's important" I heard Papyrus call me and I sprang out of my bed good thing I slept in my clothes last night. I ran down to Papyrus and saw a monster that looked like he would kill everyone here. "Who is this" I asked Papyrus, and Papyrus just looked at me like he was asking the same thing. "What do you want" I asked the monster "I'm here to finish unfinished business" he said coldly, "what business" I said full of curiosity. "I'm looking for a baby girl about a month or two old, (S/C), and (E/C)" he said, his voice put a chill down my spine. "Why are you looking for her, is she your daughter" I asked with suspicion "I'm her caretaker" he simply said. All of a sudden I heard (Y/N) crying so I went and grabbed her and brought her downstairs. "Is this her" I asked, the man smiled evilly "yes that's her" I had a felling that this guy was up to something. "Where are you talking her" I asked "I'm taking her to her mother she'll be in good hands" he said trying to take her from me. "Her mother is dead" I said with a stone face, "w-what" the monster started to get nervous, "her mother is dead I found her by her dead mother. "I knew I should have killed them both the second I saw them" he said angrily "so your the one who killed her mother" I said in a angry tone. "Why do you care I know you don't care for humans" he said "that doesn't give you the right to kill them" I retaliated "but you did" the monster said with a evil smirk. I froze I didn't know what to say I have killed humans before, I had no right to take there life, so I'm going to save one "Go away and never come back here" I said sounding threatening. The guy started to walk away and we slammed the door and (Y/N) started crying from the nose I looked down at her and tried to calm her "shhhhhh it's ok (Y/N)" I said as I rocked her. She started to calm down and I sat down in the silence for what felt like hours when (Y/N) started to coo at me I held her to my head and kissed her.
"I love you (Y/N)"
