Both, you and him were arguing, after an attack from some heroes he began to blame you for everything, then you got mad and answer back at him, what he didn't expect was all the slurs you used against him. He's cold at the outside, but at the inside he's too fragile and needs someone to love him. Your outburst scared him, since you were yelling at him, he could bet you were about to hit him, then you saw him crying, blood running from his scars

"Sorry, I-I d-didn't meant it"
