Karkat let out a sigh of relief when he saw the look on Tavros's face, a breath he didn't know he'd been holding in. The look of elation made a flush cross his own cheeks before he reached up to scratch the back of his neck, a little surprised that the present had gone over so well. He gave a slightly sheepish smile, glancing away.

"Like I said, I asked my aunt. I know you like Care and she suggested that book, but I didn't know if you already had it." The Gryffindor lowered his arm and placed his hands into his pockets, hunching his shoulders a little. It was a relief to see Tavros happy for a change. Honestly it was. "I really had no idea you wanted it so badly."
