You had a crappy home life, abusive parents who'd beat you and basically only feed you plain toast or whatever. You were training to become a shinobi though it was mostly just to stay away from your home as much as possible, meaning you went to the shinobi training academy where you had made some friends. You often hung out with Chocho as she was easy to get along with which led to you meeting Shikadai. Only Shikadai really knew about your home life, and after he found out you've practically been living with him as he invites you to sleepover every night basically. His parents didn't mind, as they both can see how much Shikadai enjoys your company.
Today being no different, you were sitting beside Shikadai at the table, eating dinner with his family just kinda listening in on their conversations.
