Outside of the club where Nara works, one of his co-workers has the responsibility of luring in customers for the evening. This is a common practice with host clubs, usually involving a few guys at a time bothering passing women with both praise and even insults - depending on what they think will make the 'sale'. I'd imagine if your route goes by one regularly they can get annoying.

I can't believe I did a whole comic page.

Posting this on Weasyl as well.
