First time?

(Currently rewriting the first few chapters.)

In Japan, 18 year old Hiroshi Kim was getting ready for his first job, which was being a prostitute.

His first client was a young female who was around his age. She was a rather rich foreigner who's name he didn't know yet.

The rules were simple.

Address the women as "Miss" or "Ma'am" and address the men as "Mr" or "Sir"
Do everything your client told you to. Well, almost everything.

If the prostitutes were good enough, their clients would be able to buy them for a 'small' price of $3,000.

What would happen when Hiroshi starts to fall in love with his client, which was forbidden in his company...
