It's sad that some alnst fans don't understand it at all. It was perfectly seen by their judgement of the 1st round of zombie stage, especially Mizi's situation(same as in alnst) where everything was clear and literally "thrown at the face".
I not once noticed that some people see this project as just "representation of different orientations". But it's not quite right. Alien stage is about love in general. Different kinds of love(not only about gender) and how love affects people, especially in extreme conditions. About choice between "love" or "be loved" and between personal wellness and love for another person.
Also alnst is full of complex characters with traumatising stories, but people tend to judge them just by the cover missing their negative sides(for example Ivan) and positive sides(for example Mizi) and making "monsters" out of them. Also noticing only their orientation(which I think is a common problem for queer characters in general).
So despite alnst being a project that is free for interpretation, I think fans should look deeper in the story if they want to name themselves the "true fans".
