When you and Giyuu had.. made out <3 you had left "love marks" on his neck.. He didn't notice you had left these "Love Marks" so when Shinobu told him he got embarrassed and speechless.. He immediately went to find you and you were in your room taking a nap. He walked up to your bed and basically was on your lap he was embarrassed and angry(but in a loving way..) Though he may be distanced and quiet he.. Has a somewhat soft spot for.. You..
