Xingqiu voice-over: About Yelan (Genshin Impact eng)

Have you heard the expression "same person, different face"? Ms. Yelan gives me precisely this feeling. When she came to visit my family, my father and brother treated her with respect, and she was pleasant and polite in return. She seemed like a kind and mature young lady to me. But when I saw her elsewhere, she gave a completely different impression.
