Five years.
A man and a woman stood on the rooftop shrouded in darkness. The late summer wind blew by, and a faint fragrance came from the fire in the woman's hand.
"When did you learn to smoke?"
"Five years ago, forget it."
"Quit it."
The woman looked at the man deeply and said, "I can't quit anymore, so go ahead."
White smoke blew out from the woman's red lips, covering her entire face, making her expression unclear.
