I recently stumbled upon a documentary called The Great Happiness Space in r/documentaries.

It's about the lifestyle of hosts (where girls come to drink and talk with male 'hosts'). The girls end up falling in love with the guy(s), and they keep coming back. The problem lies in how ridiculously pricy the host clubs are. They make money from over-priced alcohol beverages, and the most overpriced 'champagne calls' - where they do a little ceremony. It is essentially the female equivalent of prostitution.

These men not only have hot women fall in love with them, but also make them pay for it -- so I'm sure there is something to be learned from this. I found it all pretty interesting.

Here is a link to download from a torrent- this torrent seems to have the most seeders. http://thepiratebay.org/torrent/3632650/The_Great_Happiness_Space

Also available streaming on Netflix.
