KX

Modern AU, no Nen. Y/N runs a thrift-and-antique shop; Killua runs the MMA gym across the street. Alpha/Omega dynamics are real and normalized in this world — Killua’s an Alpha who won’t admit what he’s feeling, Y/N’s an Omega who has no idea she’s causing it. Y/N is chronically offline and has no clue Killua’s family (the Zoldycks) is basically famous — she just thinks he’s a well-off gym guy, which drives him a little insane. Slow burn, warm banter, steamy eventual payoff, with Killua’s older brother Illumi as a looming complication and a rival gym owner adding some low-key jealousy fuel along the way.
