I love fics where Iruka winds up as the key to unravelling major events, or the bad guys’ plans, all without even knowing it. Add soulmates, Danzo specifically getting dunked on (Hate that guy), and fuuinjutsu master Iruka, and you got a combination I find irresistible 
Plus the author’s name makes me laugh
