Yamamoto decides Gokudera is broken and needs to be fixed. It takes a while to find the right opening.
Gokudera’s constant growling had always kind of amused him, and he admitted that every now and then he sort of poked Gokudera just to get him going. Like playing with a cat; a few scratches were fair trade for getting to watch it flail at you. Actually, Gokudera reminded him a lot of a cat, sometimes, a feral cat that would only let one person pet him without biting, and that person was Tsuna. Even when they’d just met it had made Takeshi wonder a little how often Gokudera must have gotten kicked, to be that way, and now he was wondering more seriously.
