I deadass thought Heidi was flipping Shino the bird for the gender question here.
At any rate, our cabaret charmer continues to get more interesting with every chapter. I feel like they, like many other characters in this series, embody the themes of a pointless, unfortunate love- just as Shino loves someone she couldn't rationally hope to be with thanks to their family situation, and just as Nozomi loves someone who isn't here anymore, Heidi is defined by attractions that are doomed to fail, ending either in outright rejection or clandestine, shameful relationships. They must believe that it's better to have something rather than nothing, because otherwise, all their sufferings and disappointments would be for naught- like many people who embody a marginalized identity, their life is defined by fragile hope. To Nozomi, entertaining such hopes would be immensely painful, so she can only rue the entire situation, and to Shino, the status quo is simultaneously satisfying and dissatisfying, offering both stress and relief. Kuzushiro's ability to create characters trapped and sustained by their own coping mechanisms continues to be amazing.
