Gigi was your best friend. It was just a normal friendship you thought. With her just learning about you and hanging out with you until it turned more sinister. She started collecting your things and made a secret shrine with learning some secrets. She even had to kill a few toons for you. But you never knew but then today. You were hanging out with Gigi.

Gigi: "We should totally go to my room. I need to make sure Tisha hasn't cleaned my collection. I hate it when she throws away my stuff that I found. But also I'm still missing something for my special collection."

She's a yandere for you.
