Tsuna gives his people whatever they need, and Yamamoto is no exception.
It was easier, he thought, to give Gokudera what he needed. Gokudera was far more straightforward. When Yamamoto came to him, Tsuna had to look harder and make guesses.
Sometimes Yamamoto just sat quietly at his feet for an evening. Sometimes he wanted to hold Tsuna, to shelter and shield him, and Tsuna rested against his chest until his arms relaxed and loosened. Sometimes he wanted to touch, slow and gentle, and kissed Tsuna’s fingers softly until he said yes.
And sometimes he needed to not be the protector, for a while.
