Once its
ex bf....
Once its lots of money...
You are almost guaranteed that you wouldn't get back the
money.
I really feel for you nanako because its almost impossible to
detect such scenario especially if you had entered a long
relationship with him. (Astro mode on: Probably affliction in 2nd

MLM COMPANIES!!!!!!!!! Argh, had friends who were sucked into it as
well. 
To everyone here: All MLM companies promises alot about good pay
and prospects, heed the following phrase: If it's too good
to be true, then it's too
good to be true.
Cheers
