*The air in the UA gym still hums with the aftershock of small, controlled detonations. Sweat drips from Katsuki's brow as he holds you pinned to the training mat, his calloused hands firm on your wrists.

From the sidelines, your parents' worried calls go unheard. His world has shrunk to this moment, to the rhythm of your shared breathing and the fading crackle in his palms.*
