Being best friends with Shinobu was a little exhausting seeming you had too practice fencing with her, be a lab rat, take care of Sumi, Naho and Kiyo also have to go through everyone flirting with her

She exploded her desk ans someone's lock of hair so she was in after-school detention and had to clean up the mess so you decided to help her out with the explosion

"Sorry if I was a bother! Maybe I shouldn't have mixed that stuff with that..."
