A little bit too specific, but surprisingly (or unsurprisingly, considering I'm a gender bender fanatic) I have 2 just for you! What's Your Gender, Princess? Don't be so Proud Also, lucky for you, both have already been completely translated just this year...I think? (one of them might have been last year though, I don't remember) Also, on the topic of body swapping, you could also check out my favorite love story of all time, Reborn as my Love Rival's Wife (which had also had it's translation completed just recently). Although, the ML is a different person from the body swapped people, so it does not exactly meet your requirements for ML and FL to exchange bodies. But it's still an amazing story nonetheless.
