What episode is Wei Zixian and Nezha?

The end result is that the two of them ate the old gentleman's forgetfulness pill and forgot each other. Finally, although I recovered my memory, I still didn't get together! ! ! Because immortals can't fall in love, so sad! ! !

And Wei Zixianzi's episodes are 3, 4, 5, 6, 7, 8, 14 respectively, and the last episode has also appeared.

The confession episode should be the eighth episode.
