In most seasons of Big Brother, we see at least one showmance, or a romantic relationship between two houseguests. This isn’t surprising since casting tries to find a couple of attractive houseguests every season. The reality TV show requires them to live in the same house, and there is hardly any entertainment to help them pass the time. So proximity, attraction, and opportunity can lead to a hook-up if not a full-on relationship.
Lots of boundaries are being tested in the flirtation department on Big Brother 25.
