Realization
Nagisa remembers his realization: remembers being ten and surfacing from his laps to find Makoto waiting for him.
"That was really good, Nagisa-kun." Makoto extended his hand, like he did for Haru. "Coming out?"
Nagisa beamed - "Sure!" - and took it.
Something electric bolted down his arm. Stunned, Nagisa let go - falling back into the pool with a splash and spluttering as he surfaced. What was that?
"Nagisa! Are you alright?"
Nagisa looked up. Makoto's eyes were wide and worried, and something warm fizzed in Nagisa's stomach.
Oh.
"I'm fine," he said, and gave his biggest smile. "Help me out?"
