Little Devil Pestering

This kid is really tough! Fifteen years ago, she, Lard, thought she had picked up a cute and sensible little brother of a tragic aristocrat. He was precocious and told her that he had someone he liked when he was only ten years old, and that person was three years older than him. He lost money. At his eleventh birthday party, he actually wanted to propose to the girl he liked with a diamond ring worth millions. He also told her that this was just a small case. When he grows up, he must give the girl he loves more expensive and better things! Well, no matter what he does, he is her brother and of course he must support him. She helps him plan to chase girls and help him find witnesses at the birthday party in case the girl he likes doesn't admit it, but - Why does this cute, sensible, tragic, precocious and wealthy aristocratic little brother like the person she is? Mamma Mia, isn't she shooting herself in the foot? The day after her confession, he flew back to England, and she carefully wished him a safe journey and never come back again. Obviously none of the gods in the sky heard her prayers. He actually came back fifteen years later! Damn it! How many times had she told him that he was not her cup of tea! Conception:
