According to the website of Netease Yun Ge, the lyrics "You and He are still lingering" come from the song "Broken Silk", which is a song performed by a great philosopher and comes from his album "Determined to Forget You".
Part of the lyrics of the song are as follows: You and he are still lingering, although I am in tears, I don't want to be cheated by you again and again. I really want to see you again this time. Many years have passed since your story, but your heart is still there.
