The butler knew that these two probably had no idea about anything, hence he also taught them patiently.
"Remember, you absolutely cannot enter inside, our roles are clearly defined. Only a few servants can go in to tidy up because that's where the master and madam usually stay."
"Ah, there is a master and a madam?" Ruimei was very surprised to hear this.
The butler said, "You should know that these are things you can't tell outsiders, otherwise... No matter if you two saved the master before, your fate would be very obvious."
Ruimei quickly responded, "Yes, yes, yes, we understand, we are not the types to talk unnecessarily."
"Good, you need to know that it's like this: during the daytime you go to school, and come here to help at night. So, the wages we give you cover only half of your usual pay, and the rest offsets your tuition and living expenses. As for where you'll stay, we've arranged a room outside for you. Since you two are sisters, you'll share a room."
