Facing Alu's confusion, Li Chuntao spoke up, "Alu, that Yang Xiaocui, I'm just outwardly friendly with her, don't think I'm truly good friends with her."
Li Chuntao's words instantly made Alu understand, the miss is telling her not to be blinded by appearances. Among servants, many are particularly observant; they see who the master gets along with and try to ingratiate themselves with them. Even if they're not trying to ingratiate themselves, some servants have loose tongues and might get tricked into saying things. The miss is telling her not to do things that would upset her.
Alu quickly assured, "Miss, don't worry, if you're not friends with her, I won't try to ingratiate myself either. Even if you're friends with Lady Yang, I won't try to flattery her. I only serve you, miss, with absolute loyalty."
