Damn that went dark, would be an interesting story but I'd need a nice slice of life to not be depressed after lol

I have seen some lighter anime on the topic of when a bro is turned into a chick and then they go on a quest to turn them back as they don't want to answer the madding question:

If you best bro is turned into a fully functioning woman, is it gay to marry them as you now have your best friend who has the physical benefits of a woman but none of the negative behaviours (I joke, kinda).
