Traveler!Shiro AU
An AU where a Shiro from another reality is a self-proclaimed professional in cross-reality travelling. His rules are simple: never mess with time travel, only go through naturally occurring rifts, and never stay longer than necessary.
Then comes our Keith.
A Keith who was not dead (like the one from his reality), and who was not married and tied to the Shiro in this reality. The Shiro in this world never had to experience loosing Keith but he did. He knew how painful it was to lose the person he loved the most. It was the reason why seeing a version of himself that married someone that wasn’t Keith was unsettling… yet, he himself felt hopeful?
This was the first version of Keith that made him want to break his rule and stay.
His other self seemed happy with the way things were but he wasn’t. For the first time in a while, he wanted to be selfish. He wanted to be the Shiro that this Keith needs. If it means that he’d have to break his rules than so be it.
Keith is always worth it to him no matter which reality he was in.
This is my way of coping okay. Don’t think too much on the specifics of the world building around traveler!Shiro cuz I didn’t think it through. Also, I still have a few more thoughts about this so I dunno, I might add some more content if I’m not super busy..?
