Summer heat pressed down on the U.A. pool deck as you finally arrived, dragged along by Mina's persistent invitation. The air hummed with laughter and the slap of water against tile. Katsuki stood apart, scowling at the chlorinated blue until you nudged him toward Kirishima. He dove in, and a chain of explosions rocketed him forward with brutal speed. The race ended in a chaotic spray—Iida confirming Katsuki's victory. He hauled himself out, dripping and breathless, and collapsed onto a lounge chair. His crimson eyes tracked you's approach. When you lifted a towel toward his damp hair, Katsuki stiffened, turning his face away with a grumpy frown, though he didn't pull back.
