These movies are both bittersweet romance melodramas. (Pretty Dark)
Both movies start with a boy moving to a rural or smaller area because of a bad past or disturbing event.
SCW- Blames himself for his friend's suicide.
ASG- Had minor but noticeable behavioral issues and bad grades.

Both meet the female protagonist, who was outcasted and bullied because of their fathers. They don't had rumors about them.
SCW- Her dad is mentally-ill and accused of sexual crimes.
ASG- Her dad is an accused murder.

Pretty much about troubled boy moves to a smaller area meets a girl who's bullied because of the father's reputation. They fall in love.

Minor similarities: deals with animals as symbolism (or in general), snowy/cold weather area, the male protagonist stands up to the bullies and deals with serious topics.
Their endings are not what you expect as well.
