Has Ukraine explained how their proposed resolution to the Russia-Ukraine war would work if their referendum fails? [closed]

Ukraine has indicated that any compromise in the ongoing Russia-Ukraine war, such as declaring neutrality, must be put to a referendum after Russian troops withdraw.

[Ukrainian president] Zelenskyy has said any compromises on Donbas or agreement on neutrality must be put to a referendum of Ukrainian voters after Russian troops withdraw, while Moscow wants them sealed in a deal immediately.

Suppose Russia agrees to this and withdraws its troops while Ukraine hosts a referendum, but the referendum fails. Obviously Russia will not be happy. Has Ukraine explained what their proposed solution would be in this scenario?
