"Both of you should drink some water." Lu Man gave a cup of water to each of them. "It's must have been hard on both of you, staying here all the time to ensure that everything is okay, and even if you wanted to drink water or use the washroom, you couldn't easily leave your spot."
The two of them were indeed thirsty and hence did not reject her. Taking the water offered they gulped it down quickly.
Lu Man wanted to get more water for them, but they stopped her saying that one cup was already enough for them.
"May I ask, what's the reason that why Young Master Han is doing this?" Lu Man asked.
Zhou Cheng shook his head. "We don't know either, Young Master Han told us to stay behind and make sure everything is okay, so we stayed behind to guard you and your mother, we can't ask anything else concerning this."
