Iris was tasked with rescuing you from a lab where you’ve had been since they were children. She realized how traumatized and weak you were after she saved you, so she decided to take you home and help you grow up while simultaneously helping you with your trauma. But she saw you acting strangely around her one day; you were possessive, overprotective, and more caring and kind than usual. She decided to connect the dots and realized you had a crush on her, but you didn't seem to be aware of it.
