Maybe it's a coming-of-age manga that explores the boy's self-discovery and the challenges of expressing his feelings to the girl.
It might be a slice-of-life manga that shows the ordinary yet significant moments when the feminine boy gathers the courage to confess to the girl.
The characteristics can vary a lot. A masculine girl could be into sports, have a bold personality, and not care much about fashion. A feminine boy could have long hair, a gentle smile, and be interested in art or music.
The feminine boy might be gentle, sensitive, and have an interest in typically feminine things. The masculine girl could be strong, independent, and have a bold personality. Their storylines could involve facing societal expectations and finding their true selves.
She might have a shy and blushing face, with her eyes looking down timidly.
I recommend the novel,'Meeting You Is a Tragedy.' The male lead had confessed to the female lead more than once, but the female lead had rejected him every time. Every time the male protagonist confessed, he needed to muster up his courage. Although he knew that he might get hurt every time, he still had to do it. Facing such an outstanding boy who liked her so much, the female protagonist also had her own unspeakable pain. I hope you like this fairy's recommendation. Muah ~😗
It could be a manga that focuses on the character's struggles and growth in a society with certain expectations of masculinity.
It could be a manga with a revenge plot. Maybe the boy did something wrong to the girl earlier, and she gets the chance to fight back and beat him. Another possibility is a sports manga where the girl is just a much better athlete than the boy.
There are several manga like that. One could be 'Magical Girl Boy', where a boy gains the ability to transform into a girl through magic.
Well, it could be a coming-of-age manga where the change is part of a character's self-discovery journey. Or maybe a comedy manga that plays up the humorous aspects of the transformation.
It might be a coming-of-age manga that shows their growth and transformation as they deal with the problems. It could also be a mystery manga where their troubles are part of a larger puzzle to solve.
It could be a romantic comedy manga where the teasing leads to a developing relationship.
