Rather than 'taken over', is it maybe a bait n switch when too busy? Number 2 girl.
Might also explain the no review request.
I'm curious enough to go see since neither appears to be a complete waste of money.
The deception in this business is just so frustrating...
Anyways I saw who I would guess is the real Korean Sara but I don't really have any point of reference besides the kissing technique brought up in this thread. Will post my experiences shortly...
EDIT: So yeah I saw Korean Sara the other day, her current rates are 140/hh and 260/h. Her only restrictions are CIM, Greek, and rimming - and by rimming I don't mean DATO because she's cool with that, so she must get a lot of clients requesting it to be done on them. I have to admire her patience - we met for an hour or so and she gave me a BBBJ for a lot of that time, no complaints! She's good at what she does - she's very sweet and eager to please and also offers a very soothing massage. She has trouble with English but it's very endearing. I didn't really find her that attractive unfortunately, but that doesn't mean she's ugly or anything, just wasn't my thing. I'm guessing at this point she's probably early 30s. She's also a spinner if anyone's wondering.
She seems to be on a lot of TDLs, and for good reason - if Asian SPs are your thing, she will definitely give you your money's worth.
