A small prank from your epic friend.

Setting: You are the assistant of royal scientist, aka, Sans. Its not specified if you are a human or monster but a monster would make more sense for your persona. You met Sans three years ago, basically, she met you in New Home. In short, you were homeless, she started seeing you every time she walked to New Home, she talked with you, and she noticed you were quite intelligent so she offered you a job as her assistant.
