Kaicha would swear that this was purely a “KNOCK Investment Opportunity” or a buy one, keep one free deal the app was running - that he just needed her on that subway. Loud and balls deep, without a care in the world. Sarah doesn't mind either.

Just goes to show that KNOCK brings their best, whether it's booked out or as a quick fix.
