Wyvernian i dont necessarily think that since Helena is gay in the show wont necessarily think there will be a love triangle between her, Mei, and Diana. Most likely theyll remain friends, because we know people can stay platonic friends with the opposite gender, sooo itd probably be the same. Besides if she had a wife/gf before being transported, i mean that feels unusual to just move on so fast.

i really dont think theyll gender swap anyone. everything else in the series seems true to the original except 1. how the story goes and 2. Helena's girlfriend. Then again, its never really mentioned who Helena was interested in. So. who knows.

Personally i dont care about this change. Itdoesnt seem to affect the story, so as long as they dont change anything else, im satisfied.
