Another manga in which the male MC is effeminate, and the female MC is the actual masculine one. I get that Theo is a shota, but--even as far as shota go--he's not masculine at all. His mannerisms are devoid of such a trait; though he does stand up to what he's afraid of, he does it through great emotional turmoil--he has to squeeze his resolution out of himself; those mannerisms of his are also feminine--check the way he carries himself on page 17. His appearance is also feminine: his hair is reminiscent of a style for a little girl (though, on a woman, it is a hairstyle of diminished femininity; that Theo has it is the explanation). Furthermore, this guy wears thigh-high boots.
He seems to have been designed specifically for those guys who love so-called "DFC", those girls who could easily pass as males.
