I thought I had hung up the phone with Tatsumi, but apparently I hadn't, and I could hear soliloquies coming from my smartphone like "Shimono's voice today was super hot~" and "In the future, I want Shimono to drink the miso soup I make every day~"!?

I was teaching my classmate Tatsumi over the phone today as well. Since Tatsumi understands things quickly, I finished teaching today's material before long. We exchanged "see you tomorrow at school" and hung up the call. ——But it seems I had failed to properly press the call end button, and from my smartphone came Tatsumi's muttering: "Shimono-kun's voice today was super hot too~" and "In the future, I'd like Shimono-kun to drink the miso soup I make every day"...!? ※This is a submission for "Narou Radio Grand Prize 3." ※Also cross-posted on Kakuyomu.
