She abandoned her glasses after the first chapter and pretty much never wore them again.
The sudden magic weight-loss and face-change was weird enough, but there was no explanation for why she suddenly abandoned her glasses...
... and then suddenly these four guys start clinging to her like she is the last drop of water in the desert, just because she suddenly appealed to their inferior mundane aesthetics.
Yeah, I know it ain't really my place to judge a shoujo manga like this given I'm a thousand miles from the target audience and I only decided to start reading because the protagonist was SUPPOSED to be a curvy meganekko... but holy hell this is badly written and contrived. Plus the protagonist arguably looked better before her depression-induced change.
