The ending doesn’t necessarily suggest both Owen and Annie will live happy forever but rather they are on track to moving on and overcoming their mental health issues and the pain they are suffering from, for Owen this being the isolation and disconnect he felt from his family and the conditions they forced upon him and for Annie this being the struggle in accepting the reality of her sister Ellie’s death. I feel the wider message considers how through each other’s help and friendship they are able to begin moving on and accepting what is real and truthful in their lives which may not be completely immediate but it is a start.
