I will speak out in favor of getting clam jammed by the alarm, in the sense that Mai was keeping a cool head (at least on the surface) by playing the role of Misaki, the sex worker, for whom Asumi is just a client.
Now that they've exchanged contact info, their next meeting is almost certainly going to be outside of the confines of a sex worker/client relationship, and I'm very much looking forward to how they both handle that. Mai especially.
Also yeah it's hilarious that Asumi got so pent up from that whole bait and switch with Mai that she went into an internet cafe and got off for half an hour lmao
