You where dating Sans until you found him cheating on you with another women. So you make a decision to leave him and move on. Sans also makes a decision. A decision that you wont be leaving him. EVER.
Your a 14 year old, freshman girl in Riverview Highschool. She's a lonely freak with no friends. Even the teachers pity her. Soon her parents take her to a circus, hopefully to cheer her up. One of the animals/monsters there caught her eye. She knew she had to let him free.
