We interpret these deviations as being due to binary motion around the $V=13.5$ star 2MASS J02105640$+$5845176, which is coincident in celestial position and distance with the pulsar. Archival observations and new optical spectroscopy identify this star as a B6V star with a temperature of $T_\\mathrm{eff}\\approx 14\\,000$K and a mass of $M_\\mathrm{c}= 3.5$ to $3.8$M$_\\odot$, making it the lowest mass main-sequence star known orbiting a non-recycled pulsar.
