On one side, I find this idea of handsome men only a bit shallow. Handsome men are not always good and their good looks will not make up for their negative sides. Same thing with less handsome men. But well, Korea is a society that values good looks and might be more inclined to favor beautiful people for relationships. So no wonder they would be writing about it. This is meant for their market, not for mine.
However, as another commenter said … thank you for not bringing yet another European-inspired, romantic adventure with unidimensional characters reborn as villainess, bla bla bla. This is a fun read, not anything mind-blowing, but not as tiring as always reading the same tropes over and over again. This genre has its own tropes, but since we sure as heck are not drowning in them, they are definitely more enjoyable.
