How this would manifest itself in a sort of Young Elly series of books pitched at the Adrian Mole set is that we would have her throw herself at an endless series of unattainable males who are either bad for her or are already in a committed relationship with someone else. The writer would point out this out without actually pointing it out by having her deliberately misinterpret what girls with the body and the language are saying to her. We'd have her crying on her pillow about how all the 'good' ones were taken just because she isn't some pretty Barbie doll with perfect hair, perfect teeth, a perfect figure and perfect everything telling their selfish lies about how she's too quick to take offense and too slow to admit error and how that's why no one really wants to date her.
This thinking that if she were to be cuter, she'd be more loved would also allow the writer to hit people over the head with the body image issues that have always crippled Elly. Thanks to the habit they have of illustrating these things, we could compare the dishy little thing she really was with the butt-ugly monstrosity Elly has always seen in the mirror. Alternately, we'd have her talk about how much money it must take to make her class pictures look like a movie star when she's really Frankenstein only to have someone who's lying in a doomed attempt to make her feel good say he didn't spend a dime. Fathers are supposed to say that, darn it!
We could even have her ignore or be totally unaware of a proto-Anthony who might actually love her for who she is. Any sort of flash-forward to the present day would depict him as being a good man doing good things in the world wondering whatever happened to that poor girl who was always down on herself and angry for no sensible reason.
