I can't recall the name but there's Here's another work that had an anime where the two friends were isekaied while drunk. IIRC one was a chick magnet and the other was always ignored. The ignored one was thinking how much easier life would have been as a drop-dead beautiful girl when killed. I think you can figure out the rest.

It's on my To Read list along with one or two hundred others.
Already on my list and have read that. Put it on hold for a while since translations aren't coming out fast enough. I've read pretty much all kinds of manga/manhwa/manhua series that you could think of. Anything from action, to adventure, to romance (BG, BL, GL, etc.), to mystery, to horror. So anything that's considered pretty popular for a genre's tag on mangadex I've probably already read it. That was in fact one of the first genderswap romance series I've read after I accidentally stumbled upon this rather niche genre.
Nowadays since I've already read most of the normal romance series like highschooler romance, college worker romance, post-apocalyptic romance, etc. and have gotten kinda bored of the concept I began to read web novels of stuff like genderswap romance and I have to say some of them are really really darn good. Way better written than some of the other romance series I've seen. They perfectly balanced the romance with the plot and the story also doesn't drag on for too long. Only problem is because of how niche this genre is nobody really reads them so its unlikely for them to get manga/manhwa/manhua adaptations.
