  In this work, we consider a single-level quantum dot (QD) and a Majorana
bound state (MBS) placed at the end of a topological superconducting nanowire
(TSW). Both are coupled to the continuum and do not have a direct connection
between them. We addressed the behavior of MBS leaking phenomena and its
consequences into the QD physics in non-interacting and Coulomb blockade
regime. By employing Green's function formalism via the equation of motion
procedure, we calculate the physical quantities of interest. Our results show
that the leakage of the MBS into the continuum state is achieved and can alter
the physics of Coulomb blockade in the system through continuum-mediated
coupling between MBS and QD. As a main consequence, we found a robust and
non-trivial mechanism to accomplish a bound state in the continuum in the
system.
