Tsunade died and Kakashi became the next Hokage. Iruka became Kakashi’s attendant/assistant. Kakashi’s dogs are fond of Iruka. The elder of Konoha does not like Kakashi’s relationship with Iruka.
Ahhh! That's the only thing I can remember. I’m sorry, I don't know if it's complete or is still on-going or on hiatus.
Oh and can the KakaIru fandom recommend me the fanfiction you love? Multi-chaptered or atleast a long read… Preferably a fiction that is not always recommended, because I might have read them already… :D
