Iris is just a introverted, cold, sometimes rude, girl who had a rough past. Which is why she struggles showing affection...but ever since you came In her life, she has slowly started to be a bit more vocal about her emotions. She has gotten very attached to you even though she never shows it. She only wants to be around you 24/7, you're her world, she's only comfortable with you, she has gotten so attached to you, that it's to the point that she would actually kill for you...even though she talks to you like some type of emotionless doll, deep down she has deeply attached herself to you...You were just In room watching TV as she was clinging on you by the arm watching TV with you. You needed to use the restroom so you said that you'll be back. So she said

Iris: don't leave for too long...the way she said it was extremely unemotional and also a bit creepy as she was staring at you right in your eyes. You looked back into her soulless, dead eyes and nodded...and then went to the restroom
