Your POV
      You were friends with a scientist named Sarah! She told you about a monster scientist that studies love. She said the he needed a new test subject and she was wondering if you could help him.

      You of course said yes! Being the kind Neko you are! She texted you the information you'd need to find him. The text message read

"Name: W.D. Gaster
Lives: (random address)
Phone Number: (random phone number)
Personality: Curious, Smart, Brave, Kind, Determined"

      You arrived at the address and a skeleton at least 3 feet taller than you opened the door. "Um hi I'm Y/n my friend Sarah said that you needed help with a project! I told her I would help out so she told me to go here!" I said, he nodded.

      He motioned you to come inside so you did. He motioned you to sit down on the couch so you did. He sat down on the arm chair. "I am W.D. Gaster but for short call me Gaster! You said Sarah told you? Am I correct?" He asked you nodded.

      He nodded then pulled out a note pad "can we start now or do you want to start tomorrow?" He asked "we can start now if you'd like!" I said, your Neko ear twitched to an all of the sudden sound of rusty metal. "Sorry about that, dear!" He said worried.

      "No need to apologize I just wasn't expecting that! Heh!" Gaster nodded "first can you tell me a definition of a few words?" He asked I nodded "what does love mean?" He asked. "Love is when you feel a strong bond between someone and to never want that someone to be injured or upset!" I said he nodded writing something down on the note pad.

      "What does the word compassion mean?" He asked "compassion is sympathetic pity and concern for the sufferings or misfortunes of others." I stated he nodded again writing something down on the note pad.

      "What about the word lust? Can you tell me what that means?" He asked my face turned dark red. "Uhhh lust uh it's a descriptive word for when a couple or just two organisms in general want to uhhh go at it..." I said. That one made me a little uncomfortable. It also made me blush.

      "Can I try something?" He asked "are you going to hurt me?" I asked he shook his head no. "Ok then what is it-" you were cut off by Gaster kissing you and sliding his tongue in your mouth. You thought it was just for the project so you kissed back. But once you two pulled away. You with you didn't.

      You had a dark blush on your face. "Y/n you seem to be very uncomfortable, you can come back tomorrow!" He said you nodded "y-yeah I'll come back tomorrow!" You said before he walked you to the door. "Really quick!" He said you turned and he kissed you again but without sliding in his tongue.

      After that you and Gaster exchanged goodbyes and you left.

      The next day Gaster showed up in my room. "I want to show you something! Come with me!" You hesitated to take his hand at first but you still took it.

      You were now both at a field of flowers. It was beautiful! "Do you know how to dance?" Gaster asked "kind of!" You said he took both of your hands and started dancing with you. Then being the clumsy person you are you fell. Gaster attempted to catch you but fell on top of you. You to were in that position for a second. Your face was a tomato but then Gaster got off of you.

      Gaster gave you a hand "I am so sorry Y/n! Is your leg ok!?" He asked then picked you up bridal side and teleported you two to his house. He set you down on the couch and went to get his medical kit. When he did bring it back he also had his note pad. He put a bandage over the cut that wasn't bleeding anymore.

      He set down the note pad then said "can I try something again?" You nodded then he kissed your neck and abused it a bit then bit it not painfully giving you a small mark on your neck. Your hair kinda hid it.

      He then took the note pad and wrote something down. "I shall see you tomorrow Y/n!" He said then teleported you home. Then left you alone in the room.
