"Girl meets boy. Girl leaves boy. Boy hides girl's passport: A #ShamShuiPo love story," the accompanying Twitter caption reads.
The ad has since received dozens of comments from angry viewers who say it depicts a story of "abuse" and sends out a "terrible message" by romanticising a controlling relationship.
"Stealing someone's passport isn't romantic, it's what abusers do ... delete this," a Twitter user said.
"So he's LITERALLY covertly manipulating conditions in order to control a woman's ability to leave. That's coercion and is abusive," someone else pointed out.
The ad remains on the Hong Kong Twitter account despite calls for a ban.
