There's genderswap(Turn into a girl using supernatural or scientific means) and crossdressing(speaks for itself). Not sure about what you are trying to say.
wh.. What? Why!? So now they're being realistic? I've read so many romcoms and they all become one and fix their issues together. Unrealistic, but adorable. This is a work of fiction. Being unrealistic is excusable.
The author fucked me over, and especially itai.
