In the Comment written by Krasnikov \cite{Krasnikov:2019mrd} on our recentpaper \cite{Dai:2019mse}, the author argues that a spherically symmetricperturbation coming from a massive object located on the other side of thewormhole would just add up to the total mass of the central object, and istherefore useless as an indicator of the wormhole presence. We point out thatour Eq.~(37) represents an {\it acceleration variation} in the motion of thestar S2 due to an elliptic (and thus non-spherically symmetric) orbit of thestar on the other side perturbing the metric. This time-dependent accelerationvariation is in principle distinguishable from the original acceleration comingfrom the central object. We also point out that the author is trying to applyBirkhoff's theorem in a setup where it cannot be applied in a straightforwardway.
