Quick suggestion - either rename these last 2 chapters so that they don't have the volume, or add the volume numbers to the others, as it's a little out of order.
Man that last part hit hard. Not seeing someone you take care of as a person and instead seeing them as a ball of their issues and disabilities and the worry that comes with it is an easy habit to fall in. I really didn't expect this manga to strike such a real chord with me. God damn man
