>>348 Usually, if a girl who goes host club gets her debt pile up, her host introduce her to a loan shark. The loan shark usually charges 30% or 50% interest every 10 days. Thus she has to go to soapland or other sex industries to pay back in the end. The soapland operator in question had asked the host to introduce someone with the promise of advanced cash.
It is rare, but some soapland allows foreigners to get in for business entertainment needs of some Japanese company.
>>351 Off course, not all girls in soapland are there for their debt. Some of them are for their ill health parents, for their dream like to have their own store/shop, for earning academic fee, etc.
I think soapland is a necessary evil. They may have been contributing to the Japanese low sex-related crime rate.
