Even though the LHC searches did not unveil the new physics particles so far, observations made at LHCb and the $B$-factories point towards lepton flavor universality violation in both tree-level and loop-induced $B$-meson semileptonic decays. A minimal solution to this problem is to combine two scalar leptoquarks (LQ) with $\mathcal{O}(1~\mathrm{TeV})$ masses. We will show that there are only two such scenarios that are consistent with both low- and high-energy constraints, and they are given by a combination of the scalar $S_3=(\bar{3},3,1/3)$ with $R_2=(3,2,7/6)$, or with $S_1=(\bar{3},1,1/3)$. We will discuss the main opportunities to test these two scenarios in current and future experiments. Particular emphasis will be given to Lepton Flavor Violation in low-energy processes.
