We study $R^2$ gravity in $(2+\epsilon)$-dimensional quantum gravity. Taking care of the oversubtraction problem in the conformal mode dynamics, we perform a full order calculation of string susceptibility in the $\epsilon ightarrow 0$ limit. The result is consistent with that obtained through Liouville approach.
