Thinking back, since Eugene didn't have a good relationship with his family, Arthur never had to worry about 'proving' himself to them. The closest Eugene could call a sister was Sophie, but Sophie had already known him long before. If anything, Sophie had been helping them to get together because of that.
These old friends of Eugene, however, had no idea who he was aside from an alpha who got Eugene pregnant from a one-night stand. He was the alpha who made the sharp, easygoing, independent young man with a bright future have a period of depression and cut contact with all of them.
Even Arthur got angry at the person who made Eugene pregnant before he knew it was him, so how would his friends feel?
If he weren't in a relationship already with Eugene, Arthur wouldn't be surprised if these friends came at him with a pitchfork and a stake.
