(Ooguri-Vafa type metric on the negative vertex) Fix $k,\alpha,\kappa$ and $0<\epsilon\ll 1$, and let $1\ll\nu\ll A^{3/8}$. Then there is an $S^{1}$-invariant Calabi-Yau metric on $M^{-}_{\nu}$ with $S^{1}$-invariant Kähler potential $\phi^{-}$,

$$\omega_{-}=\omega^{(2)}+\sqrt{-1}\partial\bar{\partial}\phi^{-},\quad\omega_{-}^{3}=\frac{3}{4}\sqrt{-1}\Omega\wedge\overline{\Omega},$$

with metric deviation estimate $\left\lVert\nabla^{2}_{g^{(2)}}\phi^{-}\right\rVert_{C^{\alpha}_{-1-\epsilon}(\mathcal{B}^{-}_{\nu})}\leq C\nu^{2}A^{-3/4}.$ The constants depend only on $\alpha,\epsilon,\kappa$ and the scale invariant ellipticity bound on $a_{p\bar{q}}$.
