After meeting a strange woman at night, my originally ordinary life changed...
"Don't look back, run forward."
"Who are you anyway?"
"Do we know each other?"
"I seem to have seen you somewhere."
"You are not her."
Philosophy: They knew each other a long time ago, but she didn't remember her. She was completely different from her previous life. After meeting several people, she slowly found out what happened in her previous life.
