This might just be the insomnia talking, but ain't the only reason he keeps looking for girls elsewhere because he 'technically' keeps /finding/ them in other places? Sure it's the same girl, but she makes sure not to make a double-appearance as any one girl, so of course he'd look somewhere else, right?
... Unless somewhere inside he /knows/ it's her and cosplay is his fetish?

I mean, even the stupid WacDonalds visor looks cute. Seriously.
