The first day in Yanbei:
Chen Bei'an: I have admired the general for a long time. It is truly my honor to work with him this time.
Si Yun: There is no need to say these high-sounding words. The military camp is not as good as the capital, and words are the most useless.
On the Nth day in Yanbei:
Chen Bei'an: I saw that the general had not returned to camp for a long time, and I felt worried, so...
Si Yun: It's not important. None of these are important. I just want you to be safe.
The last day in Yanbei:
Si Yun: I love you
Chen Bei'an: I'm sorry
Purpose: Strive for lofty ideals
