I'd have to disagree. Chins is so delusional that the idea of this muscular Italian wanting her while poor Frank sitting somewhere, shaking his head and realizing he lost out on the big prize, will make her giddy, no matter that it's actually a lie. It's the same brand of giddiness that she has when she is "starting a new life", "going on a diet", "getting skinny"....and obviously, we know the truth to that. The guy she is fantasizing about does not exist.
She was obviously rejected by Frank, both on camera and probably, more brutally, off. This was likely her only hope/glimmer of a romance or intimate encounter for who knows how long, so she took it rough, even though she didn't show it. So, in her typical infantile behavior: Frank was Italian, so this fantasy guy is also Italian but better. Frank seemed slightly interested (until he met her in person), so this fantasy guy is crazy about her. Frank was average looking, so this fantasy guy is gorgeous. It's the type of mechanism that my 5 year old display.
Another reason that it's obvious she was lying in her "giddy" livestream is that when she first describes fantasy guy, she says, "Ohhhh he's Italian, you know. Hot Italian with dark hair." Then later in the stream, viewers ask to describe him, what he looks like or what celeb he looks like, and she says nonchalantly, "I don't really know how to describe him, he doesn't really look Italian." Then, later in the stream, she says "Oh, he has gorgeous long hair." So, a dark handsome guy with long hair that doesn't look Italian?? Sure, Chan. The way she is taking this fantasy and running with it, obviously enjoying the lies and the attention they are getting, is actually really sad to me. Send all the pompoms my way, but this level of sadness and loneliness actually gets to me a bit.
