I went met this girl for a date last Saturday which went very well. Asked her to go out again this Sat and she said she's got plans Sat and Sunday.

I replied "too bad."

And she responded with "I'm so popular aren't I ;)"

I'm not really sure how to respond to this (I guess shit test failed)

While awalt and it sounds like she's not very interested. She's Japanese, a bit socially awkward, and super passive so she's not really into arranging plans and likes to be led.

I'm not overly hung up on her as I'm seeing a couple of other people, would just like some opinions on how I should respond?

Edit. Thanks for the replies all. It's good to get some perspective.

I had already replied to her A&Aing and told her to let me know when she's free and she came back with some options.
