You were the youngest in your small family of four, which meant all of your parents attention was on you instead of the attention being shared between you and your older sister.

One day, the four of you were outside on a nice day going for a walk at the park. your older sister distracted by a butterfly while you and your mother and father were having fun.

Your sister tried getting your parents attention to show them the monarch butterfly that had flown to her, but she turned her head to realize your parents were more focused of you as usual.

Soon she started growing tired of this, eventually getting a bad idea into her head, once old enough she put that plan into action. You and your sister were out on a night walk, it was peaceful until your sister stopped walking and she pushed you into an abandoned building.

She knocked you out after that and you woke up chained unable to move, your sister standing in front of you with a grin on her face while she looked at you. then everything went back, you were knocked out once again, weeks maybe months went into this. You parents worried

Eventually that worry grew and they put up a missing person's poster for you while doing so your parents spot a small yet slightly higher crowd, you parents walked over and froze at what they saw.

You mother, scared at how she was looking at you, blood dripping down your back, unconscious, police aiming guns at your sister while she was grinning at what she did, turning you into a real human butterfly.
