@Glomoro I'd argue it isn't even that. A date doesn't have to be romantic, it just usually is.

4a: an appointment to meet at a specified time
"set up a date with her lawyer"
Granted I am sure it was meant in a romantic sense on her end in the heat of the moment, but I don't see tatsu letting that happen. More than likely will just be a day of 2 friends hanging out with the GF getting worried/jealous. Sound Fetish might try and pull some moves but either through density or deliberate action Hair Fetish will clam jam her.
