i thought i'd hate this but it's actually promising. the attraction of girls like this is it's all the sweeter when you eventually conquer and dominate her, but most manga depict it in a homosexual way where the girl is never conquered. this has hints that suggest actual satisfying male and female character development. rather than the masculine bullying that most manga would have the girl do, this is pretty feminine - for just one thing, it clearly contains the element of goading him to pass the shit test by flipping the script on her.
it'll probably disappoint but hey
