Suddenly one day Xiao Jiu saw an old classmate at the station on his way to high school, although he didn't know him.
Three years later, the two people, who were very familiar with each other, broke up.
Xiao Jiu: Sorry, I'm blind. Who are you?
Nan Mochen: If it's okay, I'll twist a bottle cap for you.
Intention: Not only do I pretend not to know you, I also don't let you twist the bottle cap for me.
