On the day Chen Yumo transferred to another school as a freshman in high school, Xia Ye gave him the window seat.
Xia Ye thought he was making friends; Chen Yumo thought he was hiding a secret.
Later one lost the other and the other broke himself.
On the day they reunited, he said: "Chen Yumo, long time no see."
Concept: Love is neither possession nor sacrifice, but two people becoming each other's destination side by side.
