They must be lover

I took the 37 bus to go back home after visiting Shin-gal funeral last friday night.
There were fewer people in the near last bus.
When the 37 bus entered the highway the middle-aged couple got on the bus.
They took seats after just right me smelling of liquor and whispered quietly.
Femal:"Honey~..I was too thinner lately so my boobs were poor."
        "I was thanks for your kindness...."
Male:"Did not worry about that. It was nothing. we were lover."
I endured for a long time.
At the samsung intersection, the couple hugging each other were got off and
disappeared away.
