@Bielna With Gwitch the anime studio didn't say that, a bad exec at Bandai (their producer) said that. Which didn't actually matter because as I said previously the director of the anime later said they're married. So it's very canon, unless you want to let a random homophobe that didn't actually work on the anime tell you it isn't. Plus regardless of what anyone says it's clear that they're married at the end of the series, and no meddling can change that.
@Donkey Kong Yeah I think the creators were hit with some restrictions, as is per usual with media in general unfortunately. However as I said before the whole marriage element is very important to the series overall and their relationship, along with the story the creators were going for, and also the fact that the director confirmed it at the end of the day. So even with the restrictions the fact that we have a Gundam series with a canonically married lesbian protagonist is huge.
