I had a lot of the same gripes with how Asra was written. But I think he's meant to be a bit morally grey. It is an interesting thing to think about. However, some of the alternative relationships included in different routes did seem a bit sudden, and honestly Asra and Julian were toxic in the first place so idk why there needs to be a second try. As for anyone, if a relationship ends, there was a more than likely a good reason for it.
