Hmm...Curious to see where this one goes. There's some good stuff, but I can never let myself get too hopeful.
The title is boyfriend sometimes girlfriend, so I'm going to assume he'll transform back (maybe with another kiss)
Actually my guess is they TRADED genders. That would be wild.
Nah, you can see her on page 86 reacting to what happened, still in girl form. It also seems like she knew this might happen and that's why she was so hesitant to kiss.
PSA: The idea that corsets could be so tight you would have trouble breathing is a myth.
Then why haven't they gotten back in fashion?
Why does anything go out of fashion? Sometimes there are logical reasons, other times it's just changing trends. Certainly one reason they aren't in fashion today is because of mainstream media constantly pushing the myth that they're some patriarchy-enforced torture device. For other reasons, Google is your friend.
@GestalRoyale Tagging this as spoilers would honestly be the spoiler itself. There's plenty of marriage art on the site for characters who don't get married in canon, so a casual observer would just assume this is like those.
