The ending is most likely going to be bittersweet. Def not gonna be the ‘happily ever after’ disney ending (which I’ve never been that keen on anyways) but despite how dark this series already is, the ending of last episode especially shows theres still a little bit of hope left. Even when the theme song is played in a sadder tone, that too always seems a bit hopeful. I don’t think its gonna be ‘everyone dies the end’ bc that would make a shit story ngl..
