maybe what he mean by gross.. is from Kanade pov...
i mean, let's assume for now he already fall in love with Kanade, he thinks that falling in love with her even though he knew that she's a former male is gross, or something like that..
well, now i'm interested.
I like genderswap genre, but if there's "girl's love"/yuri (especially if it's the MC main relationship), then that's a big no for me.
