Love is a feeling or an attraction towards the opposite sex. So.. the qualities include the features you get attracted. i.e. beauty. So.. she should be beautiful. Boys like the innocent girls. But too much innocence is also bad, as you can't live in this society. The other feeling in love is that you want to keep her for yourself. So.. the boys do not like girls admiring other boys. That's selfish, isn't it. But, love has the features of attraction, and selfishness (want to keep her for yourself).. Another part of love.. sacrifice.. when you develop a true/ understanding relationship, then you would be ready to sacrifice for the other.. So.. these are just basics... Basic instinct.. ha. you can't explain them exactly in words.. isn't it.
