In this work, we study systems composed of a 
and 
meson pair. We find three bound states in isospin, spin-parity channels 
, 
, and 
. The state with 
can be a good candidate for the 
. We also study the 
system, and a bound state with mass 5728 MeV and width around 20 MeV is obtained, which can be identified with the 
resonance. In the case of 
, one obtains repulsion and, thus, no exotic (molecular) mesons in this sector are generated in the approach.
