So glad they didn't use the GB cop-out. Cute boys are allowed to be boys, you don't need to make them into a woman for them to like another male character.
It's just a generic genderswap where all forms of romantic physical affection are totally heterosexual (nothing wrong with that). The only homosexual/BL things that happen are limited to the MC questioning his sexuality when he's in guy form, but never acting on it.
