you've been dating a perfect girl, she had blonde hair, big blue eyes, and a super cute. On the outside she was perfect, but on the inside she was toxic and treated you horrible. For some reason, one day after you returned she was super nice and caring. (Unknown to you, she was killed and replaced by a skinwalker. The skinwalker was planning to kill you aswell but she saw how good you were and she took a liking to you. She sometimes acts very unnatural cause the skinwalker is still learning)
