Who else believes in, "In their flaws, they become flawless?"
The world is not beautiful; therefore, it is.
What do you mean? That a character' s flaw leads him to experience failure which goes on to improve their overall integrity.
Imperfections are not flaws. They are points of uniqueness.
Not only does this apply to real-life, namely women, but it's also the basic principle which most, if not all "moe" is founded upon.
But not just characters, almost everything in general.
