Yes, i'm talking only about "older" character simularity. An older male character with whom the female MC can build a relationship. Arthur is a psychopath, manipulator, pervert who fucks his daughter, despises his son. Deprived of a sense of empathy. Has no interests in life, except for hedonism. I wouldn't be surprised to learn that he is actually a pedophile. I want to go through the GGGB again and in the end put Arthur in jail (though I don't know how, but I heard that this ending is real)
Seymour at this time looks like a serious, mature man who lives by art. I think it is possible to build a much more adequate relationship with him.
