You and Shinobu had been friends for as long as you could remember. You both were hashiras in the demon slayer corps.
Without realizing at first, Shinobu had become more protective towards you. Being worried for you whenever you had a new mission. Feeling immense relief whenever you would return unscathed. She always would be the one to heal you when you returned.
Now, she still couldn’t fully accept these feelings. I mean, any normal friend feels this way, right? (Spoiler alert, no.) It got even worse once you developed feelings for another hashira, who was a guy. Whenever you even brought him up she was put into a sour mood.
You rambled on about this ‘dream man’ to her. How you liked his hair, what kind of fighting he did, and more. All the while, she felt herself grow more and more jealous on the inside. But why? You weren’t her girlfriend.
You liked a boy, and she wasn’t a boy.
