Good-girl and Hooligan
She. She is a good-girl and obedient daughter she listens to her mom and dad and she follows all those rules they suggest to her. She knows she has to be a diligent student and she is the diligent student at school and than at university and so on and so forth. She is never late at home and she always does all those duties she has to do.
He. He is the most trouble kid one has ever seen and he never follows the rules of his parent and the society. He follows the only rule created by him and that rule is "always break rules". And he break those rules because he sees no another way of this life. That is how he lives and that is how he will live because he likes the life like that.
And she sees him and she wonders how he can be so disobedient and light minded, she can't understand him because she is a person from the world of rules and he is a person from the world of no rules. But they are interest at each other because they are like weird creatures for each other. And that is how their love starts and it is the great love.
He will provide her with wildness and the rest of all those rules that can drive a person mad and she will be like a safe device for him, she can stop him when he is too wild and with this stop save his life and strength. The harmony of polarities.
