A hundred years of love can cool in an instant.

I have a cousin named Amanda. She's my father's younger brother's daughter. I sympathized with her for losing her mother at an early age, and I used to help her out in various ways back then. But now I try to avoid getting involved with her as much as possible. Then one day, when I happened to see her, she was clinging to a strange man I'd never seen before, completely different from how she used to be. I think she's sick now.
