The two people who met by chance on the rooftop didn't know each other. Yes, only Sang Yu didn't know anyone. Bai Yuqi knew it was him the first time he saw Sang Yu, but he didn't say anything and later confessed to Sang Yu. Sang Yu definitely didn't expect that the person in front of him was the person he thought about day and night. When he found out, he would definitely shed tears and snot on Bai Yuqi.
Intention: a sudden whim
