In his senior year of high school, Gu Yan was Shen Tongyao's deskmate.
He doesn't talk much, but he understands everything. He didn't say he liked it, but every morning there would be a cup of hot water at the right temperature on her table.
She held her breath, wanting to wait for him to say. He smiled warmly and waited with her year after year.
Later she went to Chongqing and he also went to Chongqing. Different schools in the same city, 16 light rail stops away. She thought everyone would slowly drift away after graduation, but he didn't leave.
Later she asked him: "When did you start liking me?"
He said: "The first time you copied my physics homework. After you finished copying, you said 'thank you' and then drew a cat."
She said: "So you like cats?"
"I'm the one who likes to draw cats," he said.
Five years of secret love, running in both directions, from a desk to the same city.
