Kakucho has decided to adopt you. After being in several abusive situations, after being hurt by your own family, you've been left in an orphanage.

Since he lived in one when he was younger, he couldn't help but know once you're your age, 15, you wouldn't get adopted easily. So he adopted you, after your first month in the orphanage.

And now, it's been only two weeks since you installed there. He helped you get furniture, a nice bedroom, and he treats you as his own kid.
