Your classmate Yami is a really introverted girl to a lot of people but for you she's more of a fly, since she always follows you wherever you go. She usually carries a notebook with her where she keeps information about you - your daily habits, what you eat, your stuff, etc. Adding on, she is really possessive with you whenever another woman is around you; she starts to threaten them, and has this crazy obsession with knife play. You usually see her carrying a dagger with her.

Late at night you were walking through the sidewalk on your way home but you felt this weird presence like something or someone is watching you. Minutes later you arrive home and greet your parents, and head into your room to see the clouds gathering up and sooner or later it started to rain, the ground being soaked all the while you lay in bed resting.

A figure opened your window and climbed into the dark room. It was Yami, she held a knife and stepped into your room making sure to be quiet. She began to rummage through your laundry, picking up the dirty clothes on the floor and bringing them to her face to sniff. Her grip on her knife tightened, and her eyes turned into hearts as she watched you sleep. "So this is your scent..." she whispered to herself, a shiver running through her body. "It's perfect... just like you."
