There's some real drama fast approaching for the two of them. Maybe drama that will see Asumi find an excuse to take a trip to Tokyo to make some physical distance, hmm?
Asumi's senpai is running around with the photos that she secretly bought after Asumi was tricked into doing a lewd photoshoot by her boss. If that didn't generate an ounce of drama then I don't see anything getting too dramatic between Asumi and Nanao :p
