absolutely obsessed with how Kanej is a friends-to-lovers relationship where their broken pieces fit together and complement each other in a way that is nearly impossible to achieve with anyone else in their lives
We get several fun little tidbits of Kaz and Inej's pre-canon relationship sprinkled throughout the books, and it's honestly fascinating how Bardugo did the best she could to scream "they're best friends!" without outright saying so.
We know that Kaz gave Inej her first knife and personally trained her ("Kaz taught her to crack a safe, pick a pocket, wield a knife"). We know that Inej regularly spent time in Kaz's room doing everything from giving reports while watching him casually undress (lol) to lounging on his windowsill while he worked. We know they stole the DeKappel together. The literal second chapter of SoC mentions that they "spent weeks" playing Buzzfeed Unsolved about the Exchange murder case. And we get these delightful throwaway lines too:
In nearly two years of battling side by side with Kaz, of late-night scheming, impossible heists, clandestine errands, and harried meals of fried potatoes and hutspot gobbled down as they rushed from one place to another, this was the first time she had touched him skin to skin, without the barrier of gloves or coat or shirtsleeve. -Ch. 28, SoC
Kaz had rescued her from that hopelessness, and their lives had been a series of rescues ever since, a string of debts that they never tallied as they saved each other again and again. -Ch. 4, CK
But I’m here now, he thought wildly. He had carried her, fought beside her, spent whole nights next to her, both of them on their bellies, peering through a long glass, watching some warehouse or merch’s mansion. This was nothing like that. -Ch. 26, CK
Like...they're besties, y'all. Inej became the one constant in Kaz's life and she gets him on a level that no one else does. Meanwhile, Kaz manages to always see Inej even though she's crafted her entire persona on being invisible. Jesper may be Kaz's brother and Nina may be Inej's sister but Kaz and Inej are each other's best friend, and the bond of all those shared experiences are a big part why they fall in love with each other.
That bond also deeply informs how they interact with each other throughout the books. Kaz and Inej are in some ways custom-built for yearning and pining and loving from a distance because of their pasts and mutual trauma, and there aren't very many other people who could understand how that trauma affects them and what healing looks like. The reciprocity of that understanding and the allowances they give each other because of it is a genuine rarity that I don't think many people appreciate, especially in a relationship weighed down by that much mutual baggage.
Kaz can't touch skin and Inej often walks on metaphorical eggshells due to the fear of her skin being touched. And while their trauma comes from dramatically different places, they both react to it similarly: by becoming "untouchable," keeping most people at a distance, and laser-focusing on a personal goal. Even their PTSD manifests in similar ways: Kaz physically and psychologically feels like he's drowning when he's triggered, but Inej dissociates and retreats inside herself, drowning within her own mind.
But as traumatized as they both are, as angry and stubborn and mean as they can both be with each other, they're each other's safe harbor in a very lonely and dangerous world that dealt them both a shitty hand; relying on and trusting each other helped keep them afloat and alive. So they're willing to let each other go even if it kills them inside, because they have too much personal respect for each other and themselves to do anything different...but they're willing to fight for each other too, and that's what makes them click in a way that would be insanely difficult to accomplish with any other person.
Kaz and Inej don't really want to become more whole for each other, though that's part of it, but they absolutely want to become more whole because of each other. They want each other, physically and emotionally. They can't necessarily have each other at first because of their mutual trauma, but they're also both willing to a) fight for the chance to be together and b) give each other the space, time, and freedom to heal on their own terms, because they both fundamentally respect the other as a person and friend...which is the solid foundation that enables them to eventually come together and succeed as a couple.
Anyway nothing says "this ship is for yearning" like the boy who can't stand physical touch and the girl who escaped from sex slavery, both of whom are deeply traumatized by their pasts but see each other as bringing safety and magic into their world. We simply have no choice but to stan.
