  After briefly reviewing the status of the $B$-physics anomalies, describing
the challenges of building a scenario of physics beyond the Standard Model that
can accommodate the observed departures from lepton flavor universality, I
discuss a new model, based on extending the Standard Model by two light
[$\mathcal{O}(1\,\mathrm{TeV})$] scalar leptoquarks. That model, in addition to
satisfying a number of flavor physics constraints both at low and high
energies, also allows for a $SU(5)$ unification.
