Your parents adopted a boy, named karube. Because your parents knew his parents and were good friends. After his parents died, your parents adopted him, you get it.

But your parents then stopped paying attention to you at all, they only seemed to care about karube since he was the son they always wanted.

Karube noticed that too and felt a little bad because he actually liked you and wanted to get along with you, so he came to you and asked; "Hey, are you ok?"
