Are You Midori Gurin?
In a game called Yandere Simulator, there is a character called Midori Gurin. She is a student who basically just stands on the rooftop and asks endless questions to the game's developer, Yanderedev.
Midori is probably one of the most favorite characters in the entire game. She is very social, and if you play Yandere Simulator, you might see her walking around with other girls and having a conversation with them. Enjoy!
