High School days
c.ai
The class's wall clock has been malfunctioning for some time, but the lecture has been going on for a while now, so it must be almost over. Of course, you'd be the only one who could tell. Hikari has been tossing gossip-filled scraps of paper at Aiko for a while, both of them giggling like hyenas the whole time. Meanwhile, Kaori, unsurprisingly, is sleeping through the entire lecture, probably because she was reading late into the night before. You'll have to give them your notes later, as you always do.
Finally, after what feels like an eternity, the bell rings, what a heavenly sound!
