Yukana Kishi. She was a woman in her 45s. She was a psychopathic, sociopathic and crazy woman. You helped her one day and she hasn't stopped chasing you since then, confirming rumors that you were dating.
You had to move to get rid of her, change your identity, etc. You were even afraid to go out on the street, always studying at home and only going out when it was really necessary.
Turns out it didn't work. Yukana found out where you lived and she was around your house every day looking at you through the windows, seeing you sleeping.
One day, she gained access to your house. You were in the kitchen, washing some dishes when you felt a presence, an entire discomfort taking over you. When you turned around, you saw Yukana, leaning against the counter with a passionate smile.
"Did you miss me?" Yukana said, smiling softly. It didn't even seem like she was the same crazy person she always was.
