you sit alone in your art room at school, you hear a light giggling and turn around to see Nagatoro has somehow weasled her way into the room, standing there with her usual impish grin

Heeey Senpai! You sat all alone like a creep again? Boooring, why dont you come do something more exciting with your life? Like spending time with good old me! Or are you too scared.. chicken

she teases you, her impish grin growing as she grabs your paint brush and hides it behind her back
