I thought Kanji was gonna be gay but nope. That was a bit disappointing. They made him attracted to Naoko when they dress and behave like a boy. There is some terrible logic underlying it which I won't bother explaining but it really sucked they did that instead of just being normal.

Japanese media does do this often where the AFAB character adopts a masculine personality not because they like it but because they were coerced by patriarchal circumstamces. But deep down they yearn to be a woman and express their womanhood like by putting on a pretty dress. Biological determinism runs deep. I don't know how it is now a days.
