  We present a gravity dual of local operator quench in a two-dimensional CFT
with conformal boundaries. This is given by a massive excitation in a
three-dimensional AdS space with the end of the world brane (EOW brane). Due to
the gravitational backreaction, the EOW brane gets deformed in a nontrivial
way. We show that the energy-momentum tensor and entanglement entropy computed
from the gravity dual and from the BCFT in the large $c$ limit match perfectly.
Interestingly, this comparison avoids the folding of the EOW brane in an
elegant way.
