"Sorry, I am looking for someone else. I won't go out with you."
"Okay, what about just one date ?"
Why... is this always like this ? It's like manga is incapable of doing a proper rejection.
I'm happy that Asumi was very clear with Nanao when she said she's looking for Mai. If Nanao gets a bittersweet memory from this, that's on her for making such a request and not accepting the rejection. While I'd rather have had Asumi refuse, it makes sense for her to accept, as she probably sees it as a one-time thing like all of her brothel bookings.
I hope this arc will soon be over. The whole plot with Nanao falling in love with Asumi has been pretty annoying and obviously meant to artificially prolong the story, but I'd rather we go back to the search for Mai.
