There are always a few unforgettable people or things in life that you don't want to mention or think of. Some people choose to put them in a box and keep them in their hearts. Loneliness and liquor happen to be the keys to this box. Every time they open it inadvertently, they run rampant in the body at night, and then flood into their minds to interpret the past. Some people call it "memory", and I say it is "karma."
"If you don't owe me anything in the past life, I won't see you in this life."
"We owed each other in the past life, but we meet each other in this life."
