An Yunhuai was referring to whether the other party knows what Su Nanzhi does, meaning her mysterious spiritual power and abilities.
Su Nanzhi paused for a moment, "They know."
It's very likely that they're a like-minded person or someone who encountered a similar problem that Su Nanzhi helped solve before.
An Yunhuai: "Oh."
There was no desire to continue the conversation.
Su Nanzhi: "..."
She initially thought he would ask specifically who it was, but An Yunhuai seemed to have already assumed it was someone he didn't know, furrowing his brows, lost in thought.
An Yunhuai originally brought back two books to read, but now he wasn't reading at all, just tapping away on his phone.
Until he went to the kitchen to get a drink of water, Su Nanzhi passed by and inadvertently caught a glimpse of An Yunhuai's unlocked phone screen, showing a browser search page, with the question: [How to identify a scumbag]
Su Nanzhi: "..."
