Maybe this tag could be renamed as Medea x Protagonist to fit the rest of the pairing tags featuring Gudako?

Actually renaming all protagonist to appropriate Haruno/Gudako would be probably the best idea in the long run.

From what I saw, all Hakuno's tags are appropriately tagged with "Hakuno x Character" and all works featuring Gudako were tagged with "Protagonist x Character". This was the only one that was "Medea x Gudako", hence I suggested changing it instead of changing all others to "Gudako x Character".

Oh my bad. I remembered there was 1 tagged with Gudako, but didn't remembered which, so I didn't realize it was changed already. Explains why your comment made no sense to me then.
