Using the potentials derived from vector-meson-exchanges, the KK, DK, BK, DD, BB, BD, DK, BK and BD systems are studied. Possible S-wave bound-states of two pseudoscalar mesons are discussed. We find that systems of DB, DD, BB 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^\ensuremath- system can form an atomic bound state - the kaonium. The influence of the one-meson-exchange potential on the ground-state energy of the kaonium and its decay widths to \ensuremathπ\ensuremathπ and \ensuremathπ\ensuremathη are evaluated.
