Frost Falls to Know the Meaning

[Reunion after a broken mirror/Has been planned for a long time/Bitter at first, then sweet] Jiang Xu is a physics teacher at Peking University. He follows the rules and has a cold temper. The only trouble he had was when Ye Zhenshuang was in college. But Ye Zhenshuang left after his most difficult time, and there was no news. - As an outstanding young psychological counselor, Ye Zhenshuang was invited by Peking University to become a consultant on mental health education at Peking University. In a lecture, someone asked: "Then if a person suddenly leaves, in Teacher Ye's opinion, is he suffering from psychological trauma, or does he not care at all?" The familiar voice made Ye Zhenshuang narrow her pupils and face his answer: "If it were me, I would choose to walk away. That means I don't care." - Only Jiang Xu himself knew that Ye Zhenshuang had returned to his life this time.
