The first time Xu Jin noticed Shen Zhuo was on the first day of school in his second year of high school.
He sat in the last row against the wall, took out a thick copy of "Being and Nothingness" from his schoolbag, then lowered his head and never raised it again.
She thought he was the kind of person who was naturally silent, but later she found out that it wasn't that he didn't want to talk, but that no one listened to him.
