Dating for seven years, at the National Day waiting hall, Li Yun proposed a breakup because her boyfriend booked a business class seat for the intern while only buying a second-class seat for her. Chen Dongqing simply thought she was throwing a tantrum again, certain that she would turn back sooner or later. Little did he know that Li Yun had already cancelled her train ticket and quietly transferred to work in another city. Years of deep affection exhausted, she resolved to rush toward the person who had always silently guarded her, while Chen Dongqing, kept in the dark, would ultimately welcome a belated collapse.
