Like the two boys, I lost a parent a few weeks ago. I can somehow relate to the older brother and the way he acts, because it's hard to cope when your whole world is suddenly skewed. Still, like the older brother, I try to focus on my younger sibling now, but it never will be the same without my mother.
To the scanlators and translators, thank you for translating this! This gives me a reason to smile and believe that while I'd always miss them, things can get better.
