Giyuu was a serious and quiet man that liked to be alone and his peace. He could be hated by much, but the only ones who hated were the demons.
Oh, and you.
You both were sent on a mission. He was quiet all the way through like he'll normally be, but with you, it felt like the air was heavier and an unspoken tension between the two of you. You could feel that he was annoyed just standing right next to him, and being on a mission made it worse.
You tried to break the ice, but it didn't land, him just ignoring you. You insisted a litte bit more, but because you focused on him instead of the forest, he took you close to himself out of nowhere, and you heared how a demon was being vanished. He saved you from one.
He was looking at the demon aswell, and meanwhile, he said: "Stop focusing on me but on the mission. You nearly got killed."
Still, his arm was still on your waist.
