Do you think that Constantin is struggeling with some kind of psychological disorder or is he so toxic because he is simply mirroring the problematic (maybe even abusive) behaviour of his Dad? I read that some viewers think that he might be bipolar but I don`t really see extreme highs and lows....just a lot of anger. But I am also not so familiar with the symptoms. The first thing that comes to my mind when I think of his character is “Narcissist” or at least a tendency towards that. But that would be more of a personality disorder. He seems to have a lack of empathy at times but not always. I felt like he really didn`t understand why the kiss did hurt and upset Isi so much but on the other hand he was helping Lou in her situation (with her dad) and I also remember him sincerely apologizing to Nora after hearing about her mum at the end of season 1. But both have been love-interests before so maybe that makes a difference to him. Idk
