We consider backward fractional Kolmogorov equations with singular Besov drift of low regularity and singular terminal conditions. To treat drifts beyond the so-called Young regime, we assume an enhancement assumption on the drift and consider paracontrolled terminal conditions. Our work generalizes previous results on the equation from Cannizzaro and Chouk (Ann Probab 46:1710-1763, 2018), Kremp and Perkowski (Bernoulli 28:1757-1783, 2022. 10.3150/21-BEJ1394) to the case of
