When they met for the first time when they were young, deep seeds had been planted in Chi Yihe's heart; in Huaidong High School, Chi Yihe fell in love with Li Xiyu for the first time, but I don't know whether it was the impulse of youth or the love of adolescence; seven years later, on the busy street, I recognized you at a glance, and when we met again, even though we were thousands of miles apart, we knew it was you at a glance, maybe because of the burning eyes, or maybe because of the familiar smell of each other. At that moment, putting aside my youthful ignorance and youthful impulse, I firmly believed that I love you, and that was our second heartbeat. The first heartbeat is the rising sun, the second heartbeat is the end of dusk.
Because it's you, I'm sure it's my second heartbeat.
