The grandmother of the girl is depicted as very cold and maily focused on academic achievement - without consideration for the cilds wellbeing. (Which she already did to her daughter as well)
Not exactly abuse but a cat is put in a shelter without the protagonists knowledge and is set to be put down, but saved by the protagonist. Still, i found the threat of him being put down and the fact that he was removed from his owner kind of triggering so i thought id comment abt it
the mom had committed suicide and this is kind of a major plot point. While not shown, it is discussed a lot so if you are sensitive to the subject just be aware of this before watching.
