Other than its common connotation of being cute, shy and innocent, I've read that the word kawaii can also mean lovable. I am not sure if this is what you are referring to, but if it is, I don't think you even need to have a beautiful face to be lovable. If you want to be loved by a lot of people, then it has a lot more to do with your personality rather than your physical appearance. More importantly, remember that attraction to physical looks may easily wear off, and once it is gone you'll be left with nothing. Having that said, I think a good heart and a good mind, more than anything else, can make a person lovable.
