Sans' POV
I was hiding in the corner looking at my crush. "(Y/N) looks so pretty/handsome. I want to be with her/him forever." They were talking to their friends. She/he starts walk away to their next class. I'll see you again my sweet. I start to walk off to my next class. Luckily my next class is with my darling (Y/N). She may not know but one day she/he will. After a few minutes I was in my English class. It is not my favorite but at least (Y/N). The teacher starts to talk about our lesson. Class ended and it was now lunch time. I teleported to my locker and put my stuff away. I then teleported to a corner near (Y/N)'s locker to see if they were.....safe....yeah safe. They looked so cute with their (F/C) sweatshirt, (F/C) jeans, and (F/C) tennis shoes.

She/he was done putting away their stuff. "So dreamy." I whisper to myself. (Y/N) looks at the corner where I was. I quickly scoot away so (Y/N) doesn't see me. (Y/N) looked at me. She/he actually looked at me. I pull my hoodie up and cover my face. I shrink down to the floor and sit down. I then hear footsteps coming my way. I couldn't see since I'm still covering my 'eyes'. The footsteps stop. I lift up part of my hoodie and only my right eye socket is showing. It was (Y/N)! Oh no what should I do. The dreamiest girl/boy at school is standing in front of me. "Hey." (Y/N) waves at me. Oh my gosh oh my gosh oh my gosh oh my gosh oh my gosh. She/he is talking to me. I wave back. They kneel down. "Why are you all alone?" (Y/N) said with their beautiful voice. It was music to my non-existent ears. (Y/N) is just so perfect. "Umm....."I stay silent. (Y/N) frowns a bit. "Say what happened? You look all flustered." She/he smiles. Oh gosh their smile is so perfect. "It is nothing." I replied. "Hey wait I know you. I have you in almost all my classes. Well except for Social Studies and literature. You are the class clown." Oh my gosh! (Y/N) actually knows who I am. I thought she/he wouldn't pay attention to a guy like me.

"You know me?" I ask just to make sure this is not some sort of dream. "Yeah you are Sans the Skeleton. I really think you are funny and I love your puns." Oh geez this so much to take at once. She/he loves my puns. "I'm (Y/N) by the way." She/he sticks her hand out for me to shake. I pull out my left hand. "Nice to meet you." I already know who you are (Y/N). "How would you like to eat lunch with me on the rooftop?" She/he is inviting me join lunch with them. This is the best day of my life! "Sure." She/he smiles. "That's awesome." She/he pulls me up and walks with me to the rooftop.....while holding my hand. So much to take. I blush at the feeling that I am holding hands with my crush. We eventually make it to the rooftop and sit down on a bench. She/he lets go of my hand. I'm sad since I wanted to keep holding their hand. "Do you have your lunch with you?" I just realized I eat the school's lunch. "No." I look down. Even though I am a skeleton I want to eat. "Oh....that's ok you we can share my lunch. I actually made too much food for me so we can share." I look at (Y/N) with a shocked face. She/he is willing to share their food with me. "Are you sure? I don't want-" "It's fine. Here have some brownies." She/he holds out a brownie. I take it and bite on it. It was delicious. "This is amazing! Wow you should be a chef." I look at (Y/N) they start to blush a nice shade of pink. I made my crush blush! "You really think so?" I nod rapidly.

They smile and we start to eat lunch. Later the bell rings and she/he actually got to know a little bit about me. "Oh we have to get to class." They were about to leave when (Y/N) looked back at me. "I enjoyed this. We should do it again some time. You seem like a cool guy.....well see you later." (Y/N) leaves so they can get their stuff. I teleport to my locker rethinking of what just happened. I got to spend my lunch with (Y/N) (L/N)! And she/he also wants to spend more time with me and I made her/him blush. This is heaven. I got out all my stuff for my next class. Unfortunately next is Math and she/he has Social Studies. When I was walking down the hall I see (Y/N) talking to a guy that I don't know. She/he starts to laugh. Who is this guy? What is he doing? Is he stealing (Y/N) away from me? He is not good enough for (Y/N). I am the only one who can speak to her/him. I am the only one who can make her/him laugh. I am the only one who can see her/him.
