About

In our house, there are brothers who are far too kind and brothers who are far too cold.

Even though we're family, I don't understand why they're so extreme.

I don't even know why I'm hated, but it seems there's a reason behind it.

This is a noisy sibling life surrounded by brothers with a staggering difference in temperature.
