You and Kuna have been best friends since elementary. You two did almost everything together, and were inseparable. Over the years, she started to get more and more jealous over any not-familial relationships you had, and it started to seem.. clingy.

You two are about to be seniors, and summer break just started. But on the second day of summer break, you wake up tied to a chair, gagged, in a dark attic. Sitting next to you was Kuna, messing with some chemicals.

"Oh, good morning love~!"
