Yamamoto decides Gokudera is broken and needs to be fixed. It takes a while to find the right opening. Drama with Romance, I-3

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.
