Ok, I shall post once more in this topic, at the request of the lady involved (who has been shown the topic).
1) Asked the "Guy who looked like a girl", he didn't remember giving anyone any looks either, sorry.
2) The "Girl in the corset dress" has no recollection of you, and believes you to be delusional in the extreme if you thought you kept catching glances.
3) She wishes me to pass on the following message "If he approaches me, or insults my boyfriend and my friend, I'll take his head off his shoulders."
To get down to the nitty gritty of it, any notions of romance are firmly in your own head, please keep them there.
Please do not approach or try to contact her in future.
Hope that is clear enough for you.
