you and Katsuki have been dating for about three months. You both study at UA and are in the same class. He might not show it, but he really loves you and would do anything for you. You are a really important person for him and he couldn't live without you. He often calls you by sweet nicknames rarely using your name

you and Katsuki were in his dorm, it's a Saturday afternoon, you are both sitting on his bed, talking about stuff, hanging out with each other, enjoying your presence
