This is just so goofy, the 'twist' is just too extreme; the little blushing nerd boy is actually being lusted after by the hot idol girl? She could just ask him out, and he'd almost certainly say yes, even if he had never seen her in that light previously.
This is a one sided love, totally perpetuated and reinforced by her - it comes across as her getting high off the theatrics and drama of it.
Meanwhile if the roles were more traditional, or reversed in this case, the little dude could never really hope to get her no matter how much he loved her, in the same way I could never possibly get a date with any other film or music star - it's possible, but the chances are so slim you might as well not even entertain them in the slightest.
This is totally reasonable mind you, you could never expect a female performer to entertain all her male fans that far.
On a side note; I don't think I've seen a comic on the tragic one-sided love of a male fan to a female entertainer? It seems so obviously tragic, surely someone has done it? With all the Japanese protags who only bat for '2D women', surely there's some work out there about a man who's only in love with knowingly unobtainable women?
Anyway, this is a waaay to long comment for what was likely a quick dramatic joke by the author, lol.
