Like if they were real actual people? I could be friends with both Alya and Rahat. But they would be pretty shit friends. Rahats pretty self absorbed and emotionally unintelligent and blunt, they're generally optimistic and perky which means they can come off incredibly callous to the horrors around them, it takes a conscious effort to relate to other people and their hardships.
This all can be very unlikable but then again Rahat is based pretty heavily off myself and attributes of people I like. As much as Rahat can be an asshole, they also can be a deeply caring and kind person. The love that they have for the beauty of the world easily extends to the people they care about (the select few).
Alya is most of the time a great person and great friends. They are endlessly generous, endlessly forgiving and endlessly kind, they do not hesitate to show the people they love that they are loved. They are also a little tone deaf and overzealous. But their main problem is that they can't stand doing anything that makes them a burden, they can't set boundaries, they can't have any problems, they don't need anything from anyone, they're fine.
Now obviously because they don't set boundaries, and they never ask for anything. They're never 100% happy, and because they never reflect on their problems -because they don't have any problems- it's always the other person. They gradually become distant and resentful to the person they previously cared about, which can flare up in arguments and their relationships falling apart. Alya as a person, is pretty good. They just need to go to therapy. But because they are untreated so far in the story, they'd be a person I'd have difficult feelings about in real life.
Then there's Leopold, who's named after Leopold II (Google at your own discretion, he is genuinely disgusting, and theres still people in belgium that defend him and that makes it more disgusting) and is basically space Elon musk on steroids. He is kinda fun in a Disney evil aspect, but frankly we're getting to close to Disney evil in real life for it to be fun anymore. I'm gonna have fun killing him.
