On her photos I don't see cuteness of INF* types. And she's not emotional on them, - with poker face. It's not what IEI women are in my understanding.

I don't remember.
I saw several of them.

It's possible, but doubtfuly INF*. Also she may to be extravert with some behavior shift to introversion. Like me for example - generally I get introversion in dichotomy tests (though I don't perceive myself as shy). I even have nonverbal and communication shift to LSI, what sometimes attracted EIE, ILI, etc, and what may to push away EII, IEE, ESI *sigh*. While I'm clear LSE, with Te-Si ego, IR fiting to LSE, etc. Sometimes I typed as extraverts people which described themselves as shy, mb even correctly.
