Bengoshi no Kuzu~ Epi 7

I didn't really get the deeper meaning of this epi~
it's about an old man who has died of cancer and he has left a portion of his money to a complete stranger to his family.
The family goes to court claiming that the will must have been tampered with. It turns out that this stranger was a young lady in her 20's. She claims to have fallen in love with the old man who was 39 years older than her.
The girl was abused and abandoned by her mother and stepfather when she was young, therefore she really misses her father. When she grew up, she subconciously falls in love with men older than her and resembles her late father.
So, i guess they were trying to say that age is not an important factor in love and relationships.

On the side, it was also mentioned that the old man had never did anything for himself during his life. He had no hobby or interests. He lived for others (mainlyhis childre, i guess)
but kuzu said that prehaps, living for his children was his hobby, that was his goal in life. And the fact that he left a portion of his money to a girl that he had only met once and fell in love with (well, i think the man just pitied her...) was an act that only a baka would do. but it is because the world has bakas like him that makes it a place people love and isn't willing to leave...

(mmm, that doesn't really make sense, does it~? XD)
