Possible S-wave bound-states of two pseudoscalar mesons are discussed. We find that systems of $DB$, $D\\bar D$, $B\\bar B$ and $DK$ with isospin 0 are likely to form S-wave bound states via strong interactions while the others are unlikely to be bound by the strong interaction sector alone. With the Coulomb potential, the $K^+K^-$ system can form an atomic bound state - the kaonium.
