Captain Of My Heart {Toshiro Hitsugaya X Reader}

Note: This doesn't follow any of the Bleach events or arcs, for several reasons.
There will be cursing every so often. The MC does have a stutter because I've seen so many various forms of media using the 'cute, shy nerdy character' type of stutter so I wanted to do something with it I don't see often but personally have; throwing a bit of representation out there for others with a stutter that doesn't appear often but happens more often when their emotions are heightened.
To anyone who's embarrassed by their stutter: if you have a stutter of any kind, that has it for any reason, doesn't matter how long you've had it just know that it doesn't diminish your worth and you're still amazing!

On with the book description!
You were third seat in Squad 8 and had been for a while after graduating from the academy. Captain Kyoraku and Lieutenant Nanao quickly became the family you never really had in the Soul Society. You may normally be on the more quiet side but around those you are closer to you can be quite the bubbly personality. it didn't take long after joining the 13 Court Guard Squads to make friends with a number of the Lieutenants and Captains, a few others becoming older siblings as well. Over time, you even became close to the infamously cold Captain, Toshiro Hitsugaya; not only that but you fell head over heels for him. What happens when your Captain suggests a transfer to Squad 10? Will you confess before being sent on a mission that no one truly knows how long it will take? Will things be the same after you've been gone for a while or will everything change for the worst?
