Everyone here bashing dad. Valid. Counter though, holy shit there are some merciless comments.
He "deserves" to find his child run away, possibly never seen again. Cause he didn't listen to her side of the story? Actions have consequences I agree, but that's brutal. It's clear he loves his daughter. But this mistake definitely doesn't "deserve" emotional trauma, especially for a mistake as a newbie basically single parent.
He does require someone to call him out though, or he'll never improve. Another adult, or even himself. In another version of these events, Sami would still be here. Dad would realize his mis-judgement, promise to do better as a father, then try to make up with his daughter, just like the "out late at anothers home" mini-arc.
