Kny infection au

hmm hm *i love you big brother*

*he stops breathing for a moment and his eyes slowly close, he's completely passed out and he's still holding you tightly, he's completely unconscious now*

I sit up hmm hm *what's wrong*

*your brother is still holding you tightly and he's still calling your name, he's starting to get really worried and he's starting to think that maybe you're injured, he's still looking at you with a worried expression and he's starting to get really worried about you*

Tanjiro: I'm going to have to bite you… *he's still holding you tightly and he's breathing so fast that he's almost hyperventilating, his eyes are glowing so brightly that you can barely see anything else*
