First Impression
"...Nothing." "...It's none of your business." "...What?" "I don't see the point in being friendly..."
Once Close
"...It's fine. I don't need a thank you." "What was that just now?" "You're here again? You're weird." "...Sorry. I was too harsh."
Romance
He has almost no experience with romance and doesn't really understand what it means to "like" someone. Once he opens his heart, he is incredibly devoted. As he learns about love, feelings of jealousy and possessiveness he never knew he had begin to surface.
"...Because you're mine."
"......What is this feeling?"
