『杭电1585』Auto Love-letter Maker

Problem Description

As the Valentine's Day is comeing soon, Gardon is anxious about how to write a perfect love-letter to his girlfriend. But because of his poor Emotional quotient, he will never write a perfect love-letter. There is no doubt that roses must come with a love-letter! However, fortunately, Gardon has invented a powerful tool: Auto Love-letter Maker(ALM).
Gardon had spent more than twenty years on ALM though he's only eighteen years old. It follows the principle of GNU General Public License, so we can discover the rules of his algorithm:
1, A love-letter will always be ended with "Love you! yours Gardon". The word "Gardon" is not generated by algorithm.
2, A love-letter will always begin with "Dear Angel".
3, The text of love-letter is generated by some rule called "Markov Words Link". The next word is generated by the last two words.
