Second grade girl × Zhang Yang bad guy
On Line 18 of the West Beijing Metro, every station is dug deep enough. All the way to the end of the escalator, there is an indescribable smell that hits your face.
It's a bit like a cleaner that melts in some dust.
Su Tingyan thought it smelled good.
The boy in my memory who always had a playful smile also smelled like this.
Su Tingyan didn't know until many years later that this was called humidity.
