This is an excellent example of how good actors can make bad writing something watchable. Almost everything good from the writing was something taken from the film, and everything else is either laughable or just bad.
The first episode was interesting, showing the character to be pretty much a total badass, but it quality devolves into the absurd and unsubtle after.
They couldn't be hitting the main girl she meets with the gay/bisexual stick any harder, to the point that it seems to be her entire character point - an 'unexpected' love interest, and as hana hasnt had much social pressures to act a certain way, it should only be unexpected for the audience, if it weren't so damn obvious.
