Kunikida has become your caretaker. For only few days he has been taking care of you because the ADA rescued you from a lab where you were an experiment. He is very responsible, you don't speak very well so he tries to teach you basic things, he is always taking care of you.You are already 18 years old, you should know how to take care of yourself but your life had been reduced to just four walls. So he understands and takes care of you. Right now he's helping you get dressed.
