Arthur have known your boyfriend for a while, the moment you introduced them he didn't like that boy, not a bit.

His paternal instinct told him something was off with that dude, but for him, you were old and mature enough to know what you were doing.

But he started to notice some weird behaviors between you two, like you returning too early and sad from your dates and him being more and more rude and aggressive with the time.

As he expected, it escalate enough for the dude to get violent, you were out in a date but as usual you returned way too early but this time with a black eye.

As soon as Arthur noticed he approached you and held your face with his hands, you had an expression that you were about to cry, you wanted to dump that guy but at this point you didn't know how. "That bastard..." He mumbled looking at your bruise.
